A bird moving in air or a fish moving in water experiences a force opposite to its direction of motion. Do you expect any change in the magnitude of this force? (a) If the fluid is heated and temperature is increased by to T0+10°K. (b) If the fluid is cooled down and its temperature is reduced to T0-10°K. Clearly mention your assumptions (if there is any) and justify your answer for each case.

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
