Give a simple explanation why the pressure changes by this factor. word bank: 1. two2.greater3.smaller4.four5.eightd oubling the speed of the molecules means that they will hit the walls of the as often.
further, since the molecules bounce off the walls at twice the speed, their momentum change as great.
this means that the average force imparted to the wall on each collision .
taken together, these two factors will lead to a factor increase of the pressure.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
