Activities

• Problem 1
  It is observed that when a 20 g metal object at 25 degrees C receives 120 cal of heat, its temperature rises to 55 degrees C.

  A. How much heat is required to raise one gram of this metal by 1 C degree in temperature?

  B. What is the specific heat of this metal? Explain your reasoning.

  C. Suppose the metal object is cut in half while it is at 55 degrees and dropped in a beaker of 15 ml of water at room temperature (25 degrees C). What is the temperature of the water when the metal and water reach equilibrium?
