Find out the amount of heat required to convert 1 gm of ice at -30 ⁰C to 1 gm of steam at 120
⁰C. Given the specific heat of ice is 2090 J/kg/⁰C, specific heat of water 4180 J/kg/⁰C, specific heat
of steam is 2010 J/kg/⁰C, latent heat of ice to water is 333000 J/kg and latent heat of water to steam
is 2260000 J/kg.
Plz solve it....

  1. You gave me all the info you need.
    Do it for one KILOGRAM because those are your units. DIVIDE answer by 1000 then.

    Heat the ice from -30 to 0
    30 * 2090 J

    melt the ice
    333000 J

    heat the resulting water 100 degrees
    100 * 4180 Joules

    boil the water
    2,260,000 Joules

    heat the steam
    (120-100)(2,010) Joules

    Add them up and divide by 1000 to get a gram instead of a kilogram
