6. Find the total heat required (in kJ) to raise the temperature of a 0.190 kg of ice from -16.0°C to 132°C, including the heat needed for phase changes. (Assume the substance remains at a constant volume throughout each stage of the heating process.) 590 Use the following constants: Specific heat capacities: 4.187 kJ/kgK, 2.108 kJ/kgK, 1.996 kJ/kgK for water, ice, and water vapor (steam) respectively. Latent heat of fusion=334 KJ/Kg, Latent heat of vaporization=2256 KJ/Kg %3D B)Cho

2.12 A mass of 5 kg of water is contained in a piston-cylinder device at 125 kPa. Initially, 2 kg of the water is in the liquid phàse and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 20%. a) Determine the initial and final temperatures. b) Calculate the mass of liquid water when the piston first starts moving. c) Calculate the work done during this process. d) Show the process on a P-V diagram

A piece of ice with a mass of 120 g is transferred directly from the freezer at a temperature of 8°C to a polystyrene cup containing 300 g of water at 85°C. Calculate the final temperature of the water. Ignore any heat lost to the cup and its surroundings. 14.
