Isothermal process: A change in the system i.e. Composing or expanding the gas where the temperature does not change.
Adiabatic process: An adiabatic process is one where no heat enters or leaves the system (opposite to an isothermal process because the temperature will change).

What U, Q and W mean in relation to the human body
-
Q - Qin is the food we eat and that food is used to provide us with energy and in tern translates into work.

Heat Pump
- A refrigerator or an air-conditioner unit is an example of a heat pump
- Heat pumps normally flow from cold to hot
QH = QC + W
-
This requires W, which is converted to heat
Therefore QH consist of the heat flowing out of the cold reservour QC and the work done on the heat pump W.
QH = Heat transfer to the hot reservoir
Qc = heat transfer to a cold reservoir
W = Work done to increase heat
