It is embedded in its surroundings or environment; it can exchange heat with, and do work on, its environment through a boundary, which is the imagined wall that separates the system and the environment (Figure 3.2. 1 ).

Web14 hours ago · The heat capacity of a substance is represented by the symbol 𝐶 (𝐶=𝑚𝑐), which is the product of mass and specific heat. For solids and liquids, the specific heat is unaffected by the process; however, for gases, the specific heat must be qualified by the method. Thus, it differs for operations involving constant pressure and volume for a gas.

WebJan 30, 2024 · The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances.
