Thermodynamics

Thermodynamics is the physical science that studies effect on materials bodies, also consider the heat transfer and work done on or by the bodies.

1.)State Third Law of Thermodynamics.

Ans.: Third Law of Thermodynamics states that entropy of the system approaches constant value as the temperature approaches absolute zero.

2.)What is Charles' law?

Ans.: The volume of a given mass of an ideal gas is directly proportional to its temperature on the absolute temperature scale (in Kelvin) if pressure and the amount of gas remain constant.
It is also known as the law of volumes.

3.)What is enthalpy?

Ans.: Enthalpy is the heat content of a chemical system. It is a measure of total energy of a thermodynamic system.

4.)Differentiate between Intensive and Extensive properties of a system.

Ans.: Intensive properties are those that are independent of the size of the system such as temperature, pressure and density.
Extensive properties are those that are depend on the size of the system such as mass, volume and total energy.
