Class problems 1. A bottle contains 435 ml of ideal gas, under a pressure of 1.10 atm, at a temperature of 30.0°C. What will be the volume of gas under pressure of 0.734 atm and 5.00°C? 2. Heat is applied to convert 5 kg ice at -10°C to 100°C vapor. Specific heat of ice and water are 2.05 kJ/(kg K) and 4.182 kJ/(kg K), respectively; latent heat of fusion is 333.2 kJ/kg, and latent heat of vaporization at 100°C is 2257.06 kJ/kg.

Unformatted text preview: Calculate enthalpy values involved in the process. 3. A heater is placed in a plastic bucket holding 10 kg of water at 22C. It will take 12 min for the water temperature to reach 80C. Determine the power of the heater. Ignore the heat absorbed by the bucket and heat loss to the surroundings. Average specific heat of water is 4.18 kJ/(kg C)....
