Document Summary
A sealed rigid vessel has volume of 1 m3 and contains 2 kg of water at 100 c. State 1: v1 = 1/2 = 0. 5 m3/kg from table b. 1. 1 it is 2-phase. Table b. 1. 3 between 400 and 500 kpa so interpolate. Any other reproduction or translation of this work beyond that permitted by sections 107 or 108 of the 1976 united states copyright act without the permission of the copyright owner is unlawful. A glass is cleaned in 45oc hot water and placed on the table bottom up. The room air at 20oc that was trapped in the glass gets heated up to 40oc and some of it leaks out so the net resulting pressure inside is 2 kpa above ambient pressure of. Now the glass and the air inside cools down to room temperature. Slight amount of liquid water seals to table top. Ideal gas p1v1 = m1rt1 and p2v2 = m1rt2.
