Searching up the specific heat capacities may be required for some substances in some questions.

  1. What temperature change would occur in each of the following circumstances? a. 250 g of mercury gains 1.93 kJ of heat energy b. 5.0 kg of water gains 100 kJ of heat energy
  2. Why does running hot water over a metal lid on a glass jar make it easier to open?
  3. The background universe temperature is constantly cooling. How does this temperature trend help explain the Big Bang Theory?
  4. A sample of iron is heated to 80 degrees Celsius and placed in 100 ml of water at 20 degrees Celsius. The final temperature of the mixture is 22 degrees Celsius. What is the mass of the iron?
  5. During an investigation, 200 g of silver is heated to 90 degrees Celsius. The hot silver is then placed into 300 g of ethyl alcohol that has an initial temperature of 5 degrees Celsius. Determine the final temperature of the silver-alcohol mixture.
  6. Ethyl alcohol is a liquid at room temperature. How much thermal energy is absorbed when 135 g of ethyl alcohol at 21.5 degrees Celsius is heated until all of it boils and turns to vapour? (c = 2.46 x 103 J/kgC, Lv = 8.6 x 105 J/kg)
  7. How much thermal energy is released when 500 g of steam at 100 degrees Celsius condenses into liquid water and then cools to 50 degrees Celsius?
