2. Find the heat transferred when 6105 g of ethylene glycol (C = 2.42 J/g °C) when a car radiator cools from 37.0 °C to 25.0 °C. 120-3) 3. In a purity check for industrial diamonds, a 10.25 - carat (1 carat = 0.2000g) diamond is heated to 74.21 °C and immersed in 26.05 g of water in a constant- pressure calorimeter. The initial temperature of the water is 27.20 °C. The final temperature of the system is 27.65 °C. Calculate the specific heat of the diamond. 4. A 27.7 g sample of ethylene glycol loses 688 J of heat. What was the initial temperature of the ethylene glycol if the final temperature is 32.5 °C. (C of ethylene glycol = 2.42 J/g °C)
