In quasistatic process A of Figure 20.24, an ideal gas is brought from an initial to a final state while its temperature is held fixed. In quasistatic process B, an identical gas is brought in two steps from the same initial state as in process A to the same final state. In the first step, the gas expands at constant pressure from the initial state to an intermediate state 1 , and in the second step, the gas is brought adiabatically to the final state. Is the quantity of energy transferred thermally to the gas during process B greater than, equal to, or smaller than during process \(\mathrm{A}\) ?
