**DrBob222**, Monday, April 16, 2012 at 4:38pmI assume this is frozen to ice at -50C.

These are best worked in pieces.

Within a phase; i.e. change of T in steam or water or ice is

q = mass x specific heat in that phase x (Tfinal-Tinitial),

Example:

q for moving steam from 200 C to 100 C.

q = 10.0g x 2.03 J/g x (100-200) = ?

q at a phase change.

q = mass x heat vaporization at 100C or

q = mass x heat fusion at zero C.

example:

10.0 g x heat vaporization = ?

Then add q for each segment of the problem to find the total q for the problem.
