A calorimeter is used to measure the energy released when a new exotic rocket fuel and oxidizer are burned. The calorimeter is a closed tank with the fuel and oxidizer, and this tank is located inside a larger tank of water.When the rocket propellant burns, heat from the closed inner tank is transferred to the water, and the rise in temperature of the water is used to determine the amount of energy released. A stirrer is used to stir the water; it does work per second (power) of 4.0 kW. In a one minute period the heat transfer from the inner tank to the water is 2000 kJ and the heat transfer from the water to the surroundings is 30 kJ.a) Determine the increase in the internal energy of the water in Joules.b) What is the final temperature of the water, in degrees C if the tank contains 0.1 m3 of water and was at 300 K initially ? The density of water is 1000 kg/m3 and the heat capacity of water is 1 calorie/gram-Kelvin. One calorie is 4.1855 Joules.
