H2O (l) requires the largest amount of energy to raise the temperature of 25.0g H2O of the substance from 15.0 *C to 37.0 *C. Calculate the energy.

Hg (l) has the largest temperature change when 550 g of the substance absorbs 10.7kJ of energy. Calculate the temperature change.

please explain! thank you!

  • Chemistry -

    H2O.
    q = mass x specific heat x (Tfinal-Tinitial)
    Solve for q.

    Hg.
    q = mass x specific heat x delta T.
    Solve for delta T.
