Question

address the adiabatic compression of an ideal gas in a piston (see figure). The system is the gas inside the piston. You can assume a negligible change in the center of mass of the gas (no height change) and the system is not accelerating. Simplify the energy balance and answer the following (you can staple this page to problems 2-6) The magnitude of work is... Positive Negative Zero Not enough information given After the compression, internal energy is... Greater than the initial internal energy Less than the initial internal energy The same as the initial internal energy Not enough information is given... The value of Q is... Positive Negative Zero Not enough information is given After the compression, the temperature of the gas is You cannot tell from the information given Higher than the initial temperature Lower than the initial temperature There is no temperature change delta E_p + delta E_k + delta U = Q - W

Explanation / Answer

A. Negative

B. Greater than the initial internal energy

C.Positive

D. Higher than the temperature
