The first law of thermodynamics is ΔU = Q + W. For each of the following cases, state whether the internal energy of an ideal gas increases, decreases, or remains constant: (a) No energy is transferred to the gas as it expands to twice its original volume. (b) The gas volume is held constant while energy Q is removed. (c) The gas volume is held constant and no energy is transferred to or from the gas. (d) The gas temperature increases.

(a)

To determine
The state of the internal energy when no energy is transferred to the gas it expands to twice its original volume.

Explanation

The First law of thermodynamics is,

ΔU=Q+W

• Q is the energy exchanged
• W is the work done
• ΔU

(b)

To determine
The state of the internal energy when the gas volume is held constant while Q is removed.

(c)

To determine
The state of the internal energy when the gas volume is held constant and no energy is transferred to or from the gas.

(d)

To determine
The state of the internal energy when the gas temperature increases.
