A Carnot engine uses a diatomic gas as a working substance. During the adiabatic expansion part of the cycle, if the volume of the gas becomes 32 times its initial volume, then the efficiency of the engine is:

Thermal equilibrium between two bodies means they have the same:

Clinical thermometers should NOT be cleaned or sterilized using boiling water because:

In a standard laboratory thermometer, the temperature measurement range is typically:
