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.

According to Newton's Law of cooling', the rate at which the heat is lost by a heated body is proportional to the difference in temperature between the body and the surrounding medium (when the temperatutre difference is very small). If a thermometer is taken outdoor, where the temperature is 6°C, from a room which temperature is 25C, and the reading drops 15°C in one minute, how long after its removal from the room will the reading be 8°C? after 45 secs what is the thermometer reading?arrow_forward
