Question

Two pieces of metal of equal mass, A and B, were heated to 100 degreeC and then added to two identical beakers each containing 200. mL of water at 25 degreeC. When thermal equilibrium was reached, the temperature in the beaker containing metal A was 80 degree C and the temperature in the beaker containing metal B was 65 degree C. Which of the following statements is true? The specific heat capacity of A is greater than the specific heat capacity of B. The specific heat capacity of A is less than the specific heat capacity of B. The specific heat capacity of A is equal to the specific heat capacity of B. Because the changes in temperature were not the same for the two metals, the specific heat capacities of the metals cannot be determined.
