    I got a question says "how much heat is requeired to change 3kg of ice at -9C to steam at atmospheric pressure?"

    I must do step my step the energy of each step (energy needs to heat ice to 0,energy need to change ice to water, heat water at 100 and then make water to steam)
    am gonna find 4 indivitual energys.
    Should i add them all together for the final result isnt it?
