APP2 Thermodynamic Processes

Zeroth law of thermodynamics is:

• Kinetic energy of molecules of a gas is zero

• Ideal gas does not contain molecules

• If two systems are thermal equilibrium third one is also in equilibrium

• Absolute zero temperature cannot be obtained

Transfer of heat from low temperature to high temperature is

• None of these

• Possible by doing some external work

• Possible by keeping both the bodies in contact

• Impossible
