Heat capacity

  1. Dec 6, 2007 #1
    If 0.22L of tea at 95 degrees C, is poured into a 150g glass cup initially at 25 degrees C, what will the final temperature be, assuming no heat is lost to the surroundings?

    What have you tried?

    I tried the following:
    0.21(95-T) = 150(25+T)

    and then solved for T but it did not work out

    its actually 0.22 and 0.21
