Physics
An ideal gas is taken through a complete cycle in three steps:adiabatic expansion with work equal to I25 J, isothermalcontraction at 325 K, and increase in pressure at constantvolume.
(a) Draw a p-V diagram for the three steps.
(b) How much energy is transferred as heat in step 3, and
(c) is it transferred to or from the gas?
