Solution

The entropy change will be larger for the constant pressure process.

Here's why:

  1. Entropy (S) is a measure of the randomness or disorder of a system. It is defined by the equation S = q/T, where q is the heat transferred during a process and T is the absolute temperature.

  2. For an ideal gas, the heat transferred during a constant pressure process (q_p) is greater than the heat transferred during a constant volume process (q_v). This is because at constant pressure, the gas is allowed to expand, doing work on its surroundings and absorbing more heat.

  3. Since q_p > q_v, and since the temperatures for the two processes are specified to be the same, it follows from the equation for entropy that the entropy change (ΔS = q/T) will be greater for the constant pressure process than for the constant volume process.
