A hot tub with a surface area of 25 ft2 is filled with water to a depth of 28 in. Hint: Volume is calculated as area X height (V = AX h). (2.5, 2.7, 2.8, 3.5) a. What is the volume, in liters, of water in the tub? b. What is the mass, in kilograms, of water it contains? c. How many kilojoules are needed to heat the water from 62 °F to 105 °F? d. If the hot-tub heater provides 5900 kJ/min, how long, in minutes, will it take to heat the water in the hot tub from 62 °F to 105 °F? BA A hot tub filled with water is heated to 105 °F.
