The following statements about the two materials are true: I. The mass of material A is equal to the mass of material B (mA = mB). II. The initial temperature of material A is 70 °C, and the initial temperature of material B is 10 °C. III. No phase changes occur for either material. IV. The final temperature of both materials at thermal equilibrium is 25 °C. Given the above information, label the following statements as True or False, and justify your answers in 1-4 complete sentences each (no credit will be given if you do not provide a justification for your answers). 1. [True/False] qA < 0 (negative), and qB > 0 (positive) for the heat transfer process. 2. [True/False] qA = –qB for the heat transfer process. 3. [True/False] |qA| > |qB| 4. [True/False] The specific heat capacity of material A is less than that of material B (cA < cB).
