Solve the following problems. 1. How many Joules of heat are given off when 5.0 g of water cool from 75°C
to 25°C? (Specific heat of water = 4.18 J/g*C)
2. How many calories are given off by the water in Problem 1?
(Specific heat of water = 10 col/gC)
3. How many joules does it take to melt 35 g of ice at 0°C? Cheat of fusion - 333 )
4. How many calories are given off when 85 g of steam condense to liquid water?
Theot of vaporization - 539.4 col/a)
5. How many joules of heat ore necemory to raise the temperature of 25 g of water
from 10°C to 60°C?
6. How many calories are given off when 50 g of water at ofreezes?
theat of fusion = 79 72 collo)
