A total of 74.8 J of heat is required to raise the temperature of 18.69 g of silver from 10.0 to 27.0 oC.

What is the specific heat of silver? Show the equation, your substitution, and the answer. (6pts)

Which gives up more heat on cooling from 50oC to 10oC? Show the equation, your substitution, and the answer for both. (6pts)
50.0 g of water

100.0 g of ethanol (specific heat = 2.46 J/gK)?

How much heat energy in kilo joules is required to heat all the aluminum in a roll of aluminum foil (500.0 g) from room temperature (25oC) to the temperature of a hot oven (255oC)? (Specific heat of Aluminum is .902 J/(g x K) Show the equation, your substitution, and the answer. (6pts)
