Thermodynamics & Heat

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

Human body is a __________________ system

• open

• closed

• isolated
