- When two bodies of different temperatures and masses are put in contact, a the hotter body heats up and the colder body cools down until they reach the same temperature. b the hotter body cools down and the colder body heats up until they reach the same temperature. c the less massive body cools down and the more massive body heats up until they reach the same temperature. d the more massive body cools down and the less massive body heats up until they reach the same temperature.Q2.3 Solar houses are designed to retain the heat absorbed during the day so that the stored hear can be released during the night. A botanist produces steam at 100 during the day and then allows the steam to cool to 0 °C and freeze during the night. How many kilograms of water are needed to store 200 kJ of energy for the process? (Use the laten heat of vaporization of water L. = 22.6 105 J/ Kg, the laten heat of fusion of water Lr= 33.5 × 104 J/Kg, and the specific heat capacity of water c = 4186 J/kg. C. Hint: you need to use both the formula of the heat Q = mcVT and Q = mL)P9 E4

- When heating water for cooking food, it is common to use an electric or natural-gas cooktop. A metal pot with radius r=0.11m is filled with water to a depth of h=0.16m and heated on such a cooktop. The water is initially at a temperature of T0=25∘C. a. Enter an expression for the amount of heat required to raise the temperature of the water to its boiling point of Tv=100∘C in terms of r, h, T0, Tv, ρ and c. b. Calculate the amount of heat, in joules, required to raise the temperature of the water to its boiling point. Water has a density of ρ=1.000×103kg/m3 and a specific heat of c=4.186×103J/(kg⋅∘C) c. According to the U.S. Energy Information Administration, the average cost of electricity in the U.S. is about $0.10 per kilowatt-hour, or $0.028 per megajoule of electrical energy. Assuming all the electrical energy goes into heating the water on the cooktop, how much does it cost, in dollars, to heat the pot of water with electricity? Ignore the heat required to raise the temperature…A Pyrex baking dish with a mass of 545g warms up by 96.7 eC when it absorbs s0.9 kJ of heat an oven.
