A cyclic process on an ideal gas is shown in the pV diagram. The gas is brought

Question

A cyclic process on an ideal gas is shown in the pV diagram. The gas is brought back to its initial state after 1 cycle. If the process is carried out in a clockwise manner (as the arrows on the diagram indicate), the change in energy after 1 cycle is: a) Positive b) 0 c) Negative d) We need to know the initial state to answer 4) A thermally isolated system is prepared with a hot piece of aluminum and a cold piece of copper that are brought into contact. The specific heat of copper is less than half that of aluminum. Which object experiences the greater magnitude of heat gain or loss during the time it takes the system to reach thermal equilibrium? a) The aluminum b) The copper c) Neither. They experience the same size gain or loss of heat d) We cannot say, since we need to know the masses of each piece

Explanation / Answer

#3

For all clockwise process the work done is always POSITIVE

#4

One with more specific heat capacity will absorb more heat

So aluminium will absorb more heat
