A glass is cleaned in hot water and reaches a temperature of 50°C. The glass is placed on a table bottom up. The room temperature air trapped in the glass heats up to 46°C, and some of the air escapes, so that the resulting pressure in the glass is 2kPa higher than the ambient pressure of 100kPa. The weight of the glass now seals the volume. The glass and air are let to cool to 20°C. What is the pressure inside the glass?

A container of a gas is at 25°C and 270kPa. If it can withstand a pressure of 1000 kPa, at what temperature will it rupture?

A large tank is divided into two equal volumes. One half of the tank is filled with saturated water of unknown quality at temperature = 320 °F. The other half of the tank is evacuated (i.e there is nothing in it). When the partition separating the two halves breaks, the water will expand to fill the entire tank. The temperature is unchanged, and the final pressure is given below. Determine the quality of the water before the partition broke. Water isothermal jacket P=0 m = 0 Pfinal = 80-psia

A closed assembly contains 2lg of air at an initial pressure and a temperature of 140 kpa and 210 celcius. If the volume  of the system is doubled and the temperature drops to 37 celcius determine the final pressure of air.
