Homework Help: physical science

How much heat is required to raise the temperature of a 10.0 kg of aluminum by 80 degrees Celsius?

Look up the specific heat of aluminum. The units will be Calories/kg*degC or Joules/kg*degC. Multiply that number by the temperature change (80 C) and the mass (10.0 kg).

See
http://www.physicslabs.umb.edu/Physics/spring07/182_Exp_2.pdf
for additional information

Should this be the specific heat or the latent heat? I found the specific heat for aluminum is .215 cal/g and the heat of vaporization is 2500 cal/g. Are these number correct and which one do I use?

Is the formula H = mLv ???
