A glass is cleaned in hot water and reaches a temperature of 50C. The glass is placed on a table bottom up. The room temperature air trapped in the glass heats up to 46C, 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 20C. What is the pressure inside the glass?
