Tome saturated water vapor is contained in a high-pressure vessel at 600 kPa and 158.83 oC. The vapor is heated at constant pressure until the temperature reaches 300 oC. The mass of the vapor is 7 kg. Find the initial and final volumes V1 and V2 in m3. Find the boundary work done during the process in kJ.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
