Determing Enthaply change of Different Phases of Water
Enthaply Video of the following question:
2.00 grams of ice at -10 C is heated to vapor at 110 C.
What is the enthalpy of change?
(∆H fusion = 6.01kJ/mol, c of ice and vapor = 2.01 kJ/(kg ∘C), ∆H of vaporization of water=40.65 kJ/mol

Revised High School Math
10 Nov 09
Alberta Education has revised the math program for high school students in Alberta.
When entering grade 10, students have 3 choices: Math 10C, 10-3, and 10-4.
Math 10C will be for students planning to attend colleges and universities.
Math 10-3 will be for students planning to attend trade schools or seeking employment immediately after high school.
Math 10-4 will be, as Alberta Education states, for “Knowledge and Employability”.
More information can be found in Alberta Education.
