Specific heat of constant volume
WebAt constant volume, dV = 0, δQ = dU ( isochoric process) [ edit] A system undergoing a process at constant volume implies that no expansion work is done, so the heat supplied contributes only to the change in internal energy. The heat capacity obtained this way is denoted The value of is always less than the value of ( < ) WebSep 22, 2024 · Specific Heat at Constant Pressure or Volume When a solid is heated over a limited temperature range, its pressure remains constant. At constant pressure, this is referred to as specific heat, abbreviated as CP. When a solid is heated over a short temperature range, its volume remains constant.
