WebEx. delta U= (3/2)nR (delta T), delta T is 0, so the right side is equal to zero because you are multiplying the (3/2)nR by 0. This gives you the negative work (or Wout). So, for adiabatic delt U=work. If you remove pebbles and it expands, the temperature will go down because no heat is added. This is work out, or negative work. WebFlow work is necessary for maintaining a continuous flow through a control volume. Consider a fluid element of volume V, pressure P, and cross-sectional area A as shown left.
