Homework Help: Final temperature after calories are added

  1. Apr 29, 2009 #1
    1. The problem statement, all variables and given/known data

    A 60.5g piece of lead is at 18.6oC. If 328 cal of heat is added to the lead, what is its final temperature? Do not enter units.

    2. Relevant equations
    I was trying to use 328 as the Q value and solve for delta T
    Q=mCdelta T
    HOWEVER, this wasn't working.

    3. The attempt at a solution
    Could someone please explain to me what equation I need to use and how the 328 cal are used? Thanks.

    Can you show your calculation? You say you solved for deltaT but you need to go one step further and find the final temperature. If you did that, are you making sure your units are consistent? What are you using for C?
