The temperature of a 500 gram closed system was 10 C. By an electric heater, Energy of 2000 calories is added to the closed system for 1 hr. The surrounding does work of 1000 Joule on the systems. If the final temperature of the closed system is 120 C, Given 1 calorie = 4.2 Joule (a) Estimate the power (in kW) of the electrical heater used. (b) Calculate the specific heat capacity of the iron cylinder...
