Heat phenomena

    1. The problem statement, all variables and given/known data

    An aluminum vessel hose mass is 178g contains 90g of water at 15.5°C. How many calories of heat are required to bring the water to a final temperature of 85°C? The specific heat of water is 1cal/g°C.

    Given:
    mAl=178g
    mH2O=90g
    T1=15.5°C
    T2=85°C
    cH2O=1cal/g°C

    2. Relevant equations
    Im planning to use this formula for heat quantity

    QH2O=mH2OcH2OΔTH2O


    3. The attempt at a solution

    What about the aluminum vessel? How can you heat the water without also heating the vessel?
