A family comes home from a long vacation with laundry to do and showers to take. The water heater has been turned off during the vacation. If the heater has a capacity of 50.0 gallons and a 4,500-W heating element, how much time is required to raise the temperature of the water from 20.0°C to 55.0°C? Assume the heater is well insulated and no water is withdrawn from the tank during that time
Incorrect. An insulated Thermos contains 130 cm3 of hot coffee at 88.0°C. You put in a 19.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg-K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.00 g/cm³. Number i 66.63 Units C°

A container holding 4.20 kg of water at 20.0°C is placed in a freezer that is kept at -20.0°C. The water freezes and comes to thermal equilibrium with the interior of the freezer. What is the minimum amount of electrical energy required by the freezer to do this if it operates between reservoirs at temperatures of 20.0°C and –-20.0°C? (Latent heat of fusion of ice = capacity of water = 4186 J/(kg K), specific heat capacity of ice = 2100 J/(kg K)). 333,700 J/ kg, specific heat kJ
A 300 g aluminum pot containing 0.50 L of water is placed on the 1 kg iron hot plate on an electric stove. The heating element of the hot plate is rated at 1.5 kW. If the hot plate, the pot, and the water are all at 20°C when the heating element is switched on, how long will it take until the water begins to boil? Neglect heat losses to the surroundings.
A 0.288-kg coffee mug is made from a material that has a specific heat capacity of 930 J/kg C° and contains 0.319 kg of water. The cup and water are at 25.6 °C. To make a cup of coffee, a small electric heater is immersed in the water and brings it to a boil in two minutes. Assume that the cup and water always have the same temperature and determine the minimum power rating of this heater. Number i Units
