One litre of gas A and two litres of gas B, both having same temperature 1000C and same pressure 2.5 bar will have the ratio of kinetic energies of their molecules as:

Thermofluids is the combined study of heat transfer, fluid dynamics, thermodynamics, and combustion.

The applications of Thermofluids range from efficient engine design to heating, ventilation, and air-conditioning (HVAC).
