Questions
Statement I : Air pressure in a car tyre increases during driving.
Statement II : Absolute zero temperature is not zero energy temperature.
detailed solution
Correct option is B
When a person is driving a car then the temperature of air inside the tyre is increased because of motion. From the Gay Lussac's law, P ∝ THence, when temperature increase the pressure also increases.At absolute zero kinetic energy of the molecules become zero but potential energy of the molecules of a real gas remains non zero.Talk to our academic expert!
