Thermodynamics

The first law of thermodynamics is expressed as ...

A thermodynamic process occurring at constant temperature is called ...

A thermodynamic process with no heat exchange with the surroundings is called ...

A process occurring at constant pressure is called ...

In an isochoric process, the work done by the gas is ...

The statement that heat flows naturally from a hotter object to a cooler one is the content of ...
