Homework Help: Specific heat capacity of the final temp

  1. May 7, 2005 #1
    Hi, could someone help me get started on this problem, I am having a lot of difficulty comprehending these types of problems. THanks for your help guys.

    A cup is made of an experimental material that can hold hot liquids without significantly increasing its own temperature. THe .79 kg cup has an initial temperature of 37.9 C when it is submerged in 1.17 kg of water with an initial temperature of 21.8 C.
    What is the cups specific heat capacity if the final temperature is 24.2 C.

    To get you started:

    1. Think about which way does the heat flow between the cup and water, why there is energy transfer and at what condition there is equilibrium.
    2. Assume the system is closed
    3. From the given data you can calculate the energy tranferred between the components of the system. From that you can solve for the cups specific heat cap.
