A spherical container has a constant volume, is filled with an ideal gas, and has a pressure gauge showing the pressure in the gas. The container is placed in a tub of water and after a long time the pressure gauge shows a pressure of 100 kPa and the water temperature is 50C. You decide to add some ice to the tub of water. After a long time, the pressure gauge now reads a pressure of 80 kPa. The temperature of the gas in the spherical container is closest to: 40C -40C 14C -14C not enough information to tell
