Question

When two molecules of an ideal gas collide
A.Heat is liberated
B.No heat is liberated
C.Heat is absorbed
D.There is a decrease in the total K.E

Answer 1

Before answering this question, we should first know about the ideal gas law. The representation of it is . This law was the coming together of four laws that are Boyle’s law, Charle’s law, Avogadro’s law, and Gay lussac law.

Complete answer:
The other name is ideal gas law is a general gas equation. It is the equation that represents the state of the hypothetical ideal gas. It determines the behavior of various gases with certain conditions but the drawback is that it has certain limitations. Benoit Paul Emile gave this equation in 1834, This law can be written as –
PV=nRT
Where P is the pressure, V is the volume of gas, n is the amount of substance, R is gas constant and T is the temperature of a gas.
One of the Kinetic gas theory postulates stated that there is no change in the kinetic energy into any other form of energy of the gas molecules. It remains the same before and after the collision. It is unchanged.

So, Option (B) No heat is liberated is correct.

Note:
The kinetic gas theory describes gas atoms as large materials that are in a constant rapid motion. They easily collide with each other and also with the walls of the container they are stored in. The kinetic gas theory explains the properties of a gas such as pressure, temperature, viscosity, volume, and thermal conductivity.
