Question
Part (i) A monatomic ideal gas is in a state with the volume of VO at pressure PO and temperature TO. The
following questions refer to the work done on the gas, W = -PAV.
from the following:
The gas undergoes an adiabatic expansion from its initial state (Vo. Po. To). For this process, choose what happens to the energy, heat, and work
O AU=0, Q = -W, and W<0
OAU=0, Q=-W, and Q <0
|OAU > 0, AU = Q + W, Q> 0, and W<0
O AU <0, AU = Q, and W=0
OAU <0, AU=Q+W, Q<0, and W> 0
OAU=0, Q = -W, and W = 0
|OAU <0, AU = Q + W, Q <0, and W<0
OAU > 0, AU=Q+W, Q<0, and W> 0
O AU <0, AU = W, and Q = 0
O None of these.
