Does Q exist during Constant volume process in Stirling engine? It seems like Q=E=3/2nRT? but I am not quite sure.

If the process is constant volume dW = PdV =0 so from the first law of thermodynamics (dQ = dU + dW) dQ = dU. For an ideal gas, dU = nCvdTnotojosh said:Does Q exist during Constant volume process in Stirling engine? It seems like Q=E=3/2nRT? but I am not quite sure.
Q in a constant volume process refers to the amount of heat added or removed from a system while keeping the volume of the system constant. It is an important factor in thermodynamics and is often used to calculate the change in internal energy of a system.
The formula for calculating Q in a constant volume process is Q = ΔU, where ΔU is the change in internal energy of the system. This can be calculated by subtracting the initial internal energy from the final internal energy of the system.
A constant volume process is significant in thermodynamics because it allows for the measurement of the change in internal energy of a system without the need to account for any work being done. This makes it a useful tool for understanding the behavior of gases and other substances under constant volume conditions.
In a constant pressure process, Q refers to the amount of heat added or removed from a system while keeping the pressure of the system constant. This means that the volume of the system can change, whereas in a constant volume process, the volume remains constant while Q is being calculated.
In a constant volume process, the change in internal energy (ΔU) is directly proportional to the change in temperature (ΔT) of the system. This means that if Q is positive (heat is added), the temperature of the system will increase, and if Q is negative (heat is removed), the temperature will decrease. However, the exact change in temperature will depend on the specific heat capacity of the substance being heated or cooled.
