apply the idea behind hess's law. please?
hess law is the summation of heat. as the ke-pe pe-ke changes heat is produced. therefore as the coaster ke and pe changes more heat is created and the total enthalpy is the sum of these changes
im not quite sure though, thats all i can remember from hess law
