    Answer the following question on the basis of the information given in the table below.

    5 kg of water is supplied with an energy of 1890000 J. The increase in temperature of water is ____ K.

    hintHint:

    Use the formula Q = mS dT

    The correct answer is: 90

      • Using formula Q = mSdT
      • here Q = 1890000 J ; m = 5kg ; S = 4200 and dt = ?
      • 1890000 = 5x4200xdT
      • solving for dT we get dT = 90 kelvin
