"Web12 sep. 2024 · When the gas expands by d V, the change in its temperature is d T. The work done by the gas in the expansion is d W = p d V; d Q = 0 because the cylinder is insulated; and the change in the internal energy of the gas is d E i n t = C V n d T. Therefore, from the first law, C V n d T = 0 − p d V = − p d V so d T = − p d V C V n. " - Lowest thermal expansion gas
