What's the difference between the two formulas and for what problems do you use each formula for? I previously thought that q=mH was only used for finding the ENERGY needed to heat, freeze and boil H20, and q=mC delta T was used to find how much HEAT was needed to heat something up. I was doing a chemistry problem where it asked me to find the energy needed to raise the temperature of 1.0 mol of Ag, and the info given was very similar to the q=mC delta T formula, even though I was trying to find the energy, not the heat. I then looked online for help, and everyone used the 1=mC delta T formula. What is the difference between the two? Thanks!!!

q = mH is energy needed for a phase change to occur (no temperature change here), other is energy needed to change the temperature by an amount.
