WebSep 9, 2024 · This shows how temperature and volume of an ideal gas vary during a reversible adiabatic expansion or compression. If the gas expands, the temperature goes down. If the gas is compressed, it … WebThe air temperature is maintained constant by heat rejection to the surroundings. The rate of entropy change of air is to be determined. Assumptions 1 This is a steady-flow process since there is no change with time. 2 Kinetic and potential energy changes are negligible. 3 Air is an ideal gas. 4 The process involves no internal irreversibilities
WebAt 10 g cube of copper at a temperature T, is placed in an insulated cup containing 10g of water at a temperature T2, if T1 lager than T2, which of the following is true of the system when it has attained thermal equilibrium? The specific heat of copper is 0.385 j/g and the specific heat of water is 4.18 j/g WebThe only way the temperature's gonna remain constant is for 300 joules of heat to leave the gas, 300 joules of heat would have to leave. That would mean that Q is -300 joules, that way 300 joules and -300 joules add up to 0, you've got an isothermal process. But it's not enough for just the initial temperature to equal the final temperature.
