Interesting Chemistry Facts

"Did you know that the compound responsible for the spicy kick in chili peppers is called capsaicin? Not only does it make your mouth burn, but it also has potential health benefits like reducing inflammation and pain. #ChemistryFacts #SpicyScience 🌶️🔬"


Hello Chemistry Lovers!!!

                Here are the some interesting chemistry facts which make your day...

  1. Water is the only substance on earth that can exist naturally in all three states: solid, liquid, and gas. 


  2. At room temperature and pressure, some metals like gold and copper are so soft that they can be cut with a knife. 


  3. A diamond is the hardest naturally occurring substance known, but it is not the strongest. In fact, it is quite brittle and can be shattered easily. 

  4. Carbon, the element that forms the basis of all known life on Earth, has an incredible ability to bond with other elements. This makes it a versatile building block for molecules of all shapes and sizes.

How to Measure Temperature With a Mercury Thermometer

 How To Measure Temperature With A Mercury Thermometer

How to Measure Temperature With a Thermometer


Temperature is one of the important property which tells us so much information about substance or body. With the help of temperature you can predict in which state the material is, is it cool or hot, is it good too touch or not, thermodynamics, and even about humans you can get information like someone is well or suffering from fever etc.

Too measure temperature place tip of thermometer in substance (liquids like water, oil) whose temperature to be measured. Wait for some time. Mercury rises upside and stop rising after some time. This reading at which mercury stop rising is your temperature reading.

You can measure temperature at any scale or convert in any scale like degree Celsius, degree Fahrenheit, Kelvin etc.

Human body temperature can be measured with analog (mercury) or digital thermometer. To measure temperature of human body place thermometer under tongue or armpit. Hold the thermometer their for about 40-50 seconds then see reading on thermometer. In digital thermometer their is generally a beep sound, indicating measurement complete. So you can remove thermometer and see temperature reading on display of digital thermometer.

What is Viscosity in Chemistry

What is Viscosity in The Field of Chemistry

Viscosity
What is Viscosity
Do you know! “What is viscosity in chemistry“. To understand about viscosity, we take example of some liquids like Honey and Water. As we know honey is thicker than water. So honey flow with very slow speed on floor than water, as water is very less thick so it flows quickly. 
Hence we can say that liquids with high thickness (like honey) flow slowly and have high viscosity while a liquid with low thickness (like water) flows quickly and have low viscosity.

Example of Viscosity

To understand viscosity very well, just take few examples of viscosity in daily life.
  • Cooking Oil
  • Honey
  • Lubricant
  • Engine Oil
  • Brake Oil
  • Liquid Soap
These highly viscous liquids are some examples of viscosity in science. You known viscosity very well, even before listening this term viscosity in your physics & chemistry class.

Definition of Viscosity

Viscosity can be defined as the fluids resistance to flow.

What is Viscosity

In chemistry, Viscosity of a fluid is the measure of its resistance to gradual deformation by the tensile stress or shear stress. We can also say that viscosity is the internal resistance of the fluid. Fluids which have high viscosity resists to move as its molecular makeup gives this fluid a too much internal friction to motion, while fluids which have low viscosity resists less to move as its molecular makeup gives this fluid a less internal friction to motion.
So, we can say that molecular makeup decides internal friction between them and which ultimately provides viscosity of fluid. Honey has high internal friction than water so honey have high viscosity than water.

What is Meaning of Viscous

To understand viscosity. First, we learn what is the meaning of word “Viscous”. So, viscous is property of material i.e. material having a thick, sticky consistency between solid and liquid and also having a high viscosity. 

Who Poses Viscosity

Along with liquids or fluids, gases also have viscosity but it is very difficult to notice viscosity of gases at ordinary conditions.
We learn this chemistry topic under chemistry terminology category and Physical Chemistry Notes by Chemistry Notes Info ChemistryNotesInfo.com in simple way, we can say that, “Viscosity is the resistance of a fluid to change in its shape”,  viscosity is resistance to flow. Fluidity is the reciprocal of viscosity, So now we can say that honey has high viscosity and low fluidity while water has low viscosity and high fluidity.
Viscosity play very important role in determining characteristics of fluids used in lubrication and transportation, spraying, surface coating, injection molding etc.

Formula of Viscosity

Viscosity of any liquid can be calculated with viscosity formula. And viscosity formula is given below to calculate viscosity of any fluid or liquid.
Viscosity = Force×Time ∕Area

Newton’s Viscosity Law

According to the Newton’s viscosity law’, Shear stress between the two adjacent fluid layers is directly proportional to the velocity gradients between these two layers.

Unit of Viscosity

Unit of Viscosity is Newton second per Square meter (Ns/m2)
SI unit of viscosity is Pascal second (Pas)

Relation of viscosity with temperature

Viscosity of the liquids decreases quickly with increase in the temperature, while viscosity of the gases increases with increase in the temperature.
Temperature ->27 °C77 °C
Viscosity of Water0.85×10-3 pascal second0.36×10-3 pascal second
Viscosity of Air1.85×10-5 pascal second2.08×10-5 pascal second

Types of Viscosity

Viscosity is classified in two types. which are as follows-

1. Dynamic Viscosity

Dynamic viscosity is defined as the measure of the ratio of 'shear stress to shear rate' of the fluid.

Formula of Dynamic Viscosity
Dynamic Viscosity - Types of viscosity in science chemistry physics

2. Kinematic Viscosity
Kinematic viscosity is defined as the measure of ratio of 'viscous force to inertial force' on the fluid.

Formula of Kinematic Viscosity

Measurement of viscosity
Viscosity is measured by various types of Rheometers or Viscometers.

Forensic Science Chemistry - Famous Forensic Scientists and Forensic Chemist

Forensic Science Chemistry - Famous Forensic Scientists and Forensic Chemist

In this post we will learn about forensic science and forensic drug chemistry. Also learn about fathers of various fields of forensic science and famous forensic scientists and forensic chemist.

In this post we will learn about forensic science and forensic drug chemistry. Also learn about fathers of various fields of forensic science and famous forensic scientists and forensic chemist.

Definition of Forensic Science

Forensic science is the application of scientific methods and techniques to matters under investigation by a court of law. Almost all branches of science may contributes to solve a crime scene, hence comes under forensic science.


Forensic Drug Chemistry

Forensic drug chemistry is the sub-branch of chemistry.  Forensic drug chemistry is used in identification of matter generally illegal drugs. The Forensic chemist examines the samples bring in forensic chemistry lab. Forensic chemist tries to find the name of matter or drug by examining the atoms and molecules in matter. Also find how these atoms and molecules interact and bond with each other. As we know, all matter or drug substance has a chemical signature (Spectrum, that you study under spectroscopy) and or some physical and chemical properties which are unique to only that substance. Forensic chemists use these physical and chemical properties to identify matter or drug substances using scientific techniques or methods. Findings by examining samples are presented as facts in court. Forensic chemistry covers analysis of any matter like illegal drugs, explosives, poisons etc.

 

What does Forensic Scientists and Forensic Chemist do ?

Forensic Scientists examine and analyze evidence or matter obtain from crime scenes. Forensic chemists conduct analysis of matter forensic chemistry. While other forensic scientists do other analysis like fingerprinting, handwriting analysis, DNA, trace evidence examination, fire and explosives examinations, forensic toxicology, digital evidence and many other analysis.  After doing all analysis they develop objective findings that can assist in the investigation and prosecution of person who has done crime or release the innocent person.
