Calculate the amount of heat (in calories) required to raise the temperature of 200g of water from 20C to 50C. The specific heat of water is 1.00 cal/g.
I have done other spacific heat problems but on this one i don't know how to start...

Heat=mass*specific heat*changeinTemp
=200g*1cal/gC*30C 
6000 calories?

Go to the head of the class. Right.
