    1. The problem statement, all variables and given/known data
    there is a bath of 160L of water at 41oc (shc 4000). A rock of 15kg is dropped into the bath at 250oc with shc of 2000

    What temperature does the water end up at?


    2. Relevant equations

    Q=cmT

    3. The attempt at a solution

    Very sorry but I dont have a clue. Not really on A2 spec

    hi rugby123! :wink:

    the rock and the water will end up at the same temperature

    so use the fact that the heat gained by the water equals the heat lost by the rock …

    what do you get? :smile:
