The first law of thermodynamics confirms the concept of energy conservation. It states that energy cannot be created or destroyed, only transformed from one form to another, ensuring the total energy of an isolated system remains constant.
The function of a thermostat in a refrigerator is to maintain the same temperature. It regulates the cooling system, turning it on and off to ensure the internal temperature stays within a set range, thus preserving food at a consistent ...
In an isothermal change, the temperature of the system remains unchanged. Heat can be exchanged with the surroundings to ensure the temperature remains constant while the system undergoes expansion or compression.
In an adiabatic change, no heat is exchanged with the surroundings, so heat remains unchanged. However, the temperature of the system can change due to work done on or by the system.
