... is the sum of random distribution of KE and PE of all the molecules in the system. The substance contains internal energy, not heat. The word “heat” is used only when referring to the thermal energy actually in transit from hot to cold. 11. A flask containing boiling water is removed from the burner ...

Molar Heat Capacities of an Ideal Gas
... The warm liquid at the bottom expands and rises because of reduced density. It is replaced by cooler, denser liquid that then becomes heated and rises. Upon reaching to the top, it cools and hence sinks back to the bottom. These convection currents continue to flow through the liquid. A similar sit ...

It is not an efficiency in the usual sense; rather, it is the ratio of an actual process and an ideal process. Both proce ...
