How much heat is required to raise the temperature of 20.0g of H2O from 18.0 Celcius to 28.0 Celcius?

  • chemistry - ,

    heat=mass*specificheatcontent*deltaTemp

  • Thermal physics - ,

    We have,
    E = (mass)(specific heat capacity)(delta Temp)

    mass = 20.0/1000 = 0.02 kg

    => E = (0.0200kg)(4200J/kg C)(28.0C-18.0C)
    = 840 J
