What is the specific heat for aluminium based on calorimetry data
A 73.6 g sample of Al is heated to 95.0 C and dropped into 100.0 g of water at 20.0 C The resulting temp. is 30.0 C. What is the specific heat?
I know that sp.ht. = heat(cal) / mass x delta T
So I have the mass at 73.6 and the temp. change of the water is 10.0 C but I can't figure out what the heat calorie is to figure the sp.ht.

Re: specific heat question
what you have to realize here is the heat lost by the Al is equal but opposite to the heat gained by the water
using q = m C delta T for water (the C for water is known , 4.184 J / C ) solve for the heat (q)
take this number (q) and use the equation again but for Al
