- Your answer is partially correct. An insulated Thermos contains 110 cm3 of hot coffee at 83.0°C. You put in a 15.0 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 20 Units C°A coal-fired power plant discharges 1 m^3/s of cooling water into a river, which has a flow of 9 m^3/s and a temperature of 20 degree C. According to the regulation, the temperature in the river immediately below the discharge cannot be increased by higher than 1 degree C. Therefore, what is the highest temperature of the cooling water is allowed for discharge?What is the specific volume of oxygen at 40 psia and 80°F?
