This energy can be modified by exerting work on it or by the transfer of energy. The system's energy can change by transferring heat or work (or both) between the system and its surroundings. If positive work is applied, the system gains energy. st.thomas orthodox syrian churchWeb12 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. st.thomas school ranchi dhurwa
