20 kg of steam at 383 K transfers Q = 1.5 × 106 J of its energy to the environment. What is the mass of water that condenses? (The latent heat of fusion is Lf = 3.3 × 105 (J/kg) and the latent heat of vaporization is Lv = 2.26 × 106 (J/kg). The specific heat of steam is csteam = 2010 (J/(kg ◦C) and cwater = 4186 (J/(kg ◦C).) A) 0.0 kg B) 0.5 kg C) 7.2 kg D)...

Calculate the final equilibrium temperature when 10.0 grams of steam initially at 100 degree C is mixed with 450 grams of liquid water and 110 grams of ice at 0 degree C in a calorimeter. That is, the liquid water AND the ice are initially at 0 degree C. Ignore any heat energy exchanges with the calorimeter and the surroundings. If you conclude that the final temperature of the system is 0 degree C, then what mass of ice remains,...

You have a container holding 45 grams of water at 25.0 °C and 750-gram block of aluminum. Your goal is to heat the aluminum block so that it boils all of the water away when placed in the container. What minimum temperature is needed? Consider the water + aluminum to be an isolated system (i.e., ignore any heat flow to the environment, which includes the container). The specific heats of aluminum and water are 900.0 and 4186 J/kg°C respectively. The...
