Note the correct spelling of celsius.
There are two equations you need to do this.
Within a phase use
mass x specific heat x (Tfinal-Tinitial)
For example to change T of water from liquid water at 100 C to liquid water at 0 C, it is
mass H2O x 4.184 x (0-100) = ?
At a phase change use
mass x heat fusion at freezing point
mass x heat vaporization at boiling point.
For example, to convert steam at 100 C to liquid at 100 C it will be
mass steam x heat vaporization.
Then add each part to find the total heat transferred.
how much heat energy is released from cooling 35 grams of steam at 135 degrees celcius down to freezing it to negative 45 degrees celcius?
