Heat of Fusion and Heat of Vaporization Problems
Absorbing heat is positive, releasing heat is negative
1. How much heat is absorbed when 100.0g of ice is melted?
2. How much heat is released when 24.78g of steam is condensed?
3. How much is absorbed when 234.567g of water is boiled?
4. How much heat is released when 28.95g of water is frozen?
5. How much heat is released when 0.5g of steam is condensed?
6. How much heat is absorbed when 125.000g of ice is melted?
7. 120.0g of ice is melted, how much energy is absorbed?
8. 20000g of steam is condensed into water, how much energy is released?
9. 1.5g of water is frozen, how much energy is released?
10. 345.0g of water is converted to steam, how much energy is absorbed?
Are these changes chemical or physical?
Can you use the same equation for any other substance besides water?
Develop a step by step procedure that you can do in the lab in order to calculate (or verify) the value for the heat of fusion of ice. Include equipment that you would need. Use the back of this page, too, if necessary.
