Is Heat a State Function?
Is heat a state function? The answer is no. Heat is the energy transferred between the system and the surroundings during a process. The amount that transfers does depend on how the…

Enthalpy vs entropy -what’s the difference? All materials contain both of these thermodynamic properties. Enthalpy provides the total amount of internal energy held within a substance. Entropy measures the randomness…
The Carnot cycle is a thermodynamic cycle that represents a theoretical heat engine. The main reason why the cycle can not actually exist is that the concept relies on holding…
The Stirling cycle is a thermodynamic cycle and a variation of the Carnot cycle. Rather than undergoing isentropic processes, the cycle undergoes isochoric processes. As a truly reversible cycle, it…
The diesel cycle is a thermodynamic cycle which undergoes internal combustion. It is similar to the Otto cycle. However, the main difference is that the fuel heats by the compression…
The refrigeration cycle is a specially designed thermodynamic cycle that removes heat from a closed environment to keep the inside cool. Likewise, it provides the exact opposite effect by simply…
The Otto cycle is best exemplified by the sparkplug engine. Regularly seen in car engines and lawnmowers, this cycle is versatile in the different jobs it can do as well…
The Brayton cycle is a thermodynamic cycle that utilizes warm air as the working fluid. The cycle sees common use in jet engines, because of the flow of air and…
The Rankine cycle is a thermodynamic cycle that allows uses steam as the working fluid inside of a cycle. This contrasts with most thermodynamic cycles that use air or some…
Thermodynamic cycles are processes that involve heat and work flowing into and out of a system. These systems usually intake a working fluid and output mechanical work or energy. These…
