Consider one mole of an ideal monoatomic gas at STP and confined in a volume V1. You would like to increase its temperature by an amount ΔT.a) Where will you provide less heat to achieve your objective; at constant volume process or at constant pressure process?

In the following question, I used the q=ms(delta T) equation, and q_system=-q_surroundings, with the final temperature of water being the answer I'm solving for. With my current arithmetic I get an answer that's way off. And I think I may have my equation incorrectcly set up somehow, because when I plug in the correct answer to try working backwards, the q_system does not equal the -q_surroundings. I'm not sure why my equation would be wrong though. Isn't the final temperature the same for both sides of the equation?
