1. A copper pot with a mass of 0.500 kg contains 0.170 kg of water, and both are at a temperature of 20.0^oC. A 0.250-kg block of iron at 85.0 ^oC is dropped into the pot. What is the final temperature of the system assuming no heat is lost to the surroundings?

2. What unit is normally used to identify the quantity of a gas used in the ideal gas law equation?

3. Helium gas with a volume of 2.60 L under a pressure of 1.30 atm and a temperature of 41.0 ^oC is warmed until both the pressure and the volume of the gas are doubled. The molar mass of helium is 4.0 g/mol. What is the final temperature of the gas?

4. Helium gas with a volume of 2.60 L under a pressure of 1.30 atm and a temperature of 41.0 ^oC is warmed until both the pressure and the temperature of the gas are doubled. The molar mass of helium is 4.0 g/mol. How many grams of helium are there??

5. A certain amount of ideal gas occupies a volume V at STP on Earth. What would the volume be (in terms of V) on Venus where the temperature is 1003 ^oC and the pressure is 92 atm.

6. Two identical closed insulated containers hold equal amounts of water at 50 ^oC. One kilogram of ice is added to the water in container A; 1 kilogram of steam is added to the water in container B. After all the ice has melted and all the steam has condensed, which container's temperature will have changed more?

7. A storage tank contains 21.6 kg of nitrogen (N2) at an absolute pressure of 3.65 atm. What is the pressure if the nitrogen is replaced by an equal mass of CO2?

8. A thin metal rod expands 1.5 mm when its temperature is increased by 2.0 degrees C. If an identical rod of the same material, except twice as long, also has its temperature increased by 2.0 degrees C, it will expand:

9. A water heater can generate 7,200kcal/h. How much water can it heat from 15 ^oC to 50 ^oC per hour?

10. A 25,000-kg subway train initially traveling at 15.5 m/s slows to a stop in a station and stays there long enough for its brakes to cool. The stations dimensions are 65.0 m long by 20 m wide by 12.0 m high. Assuming all work done by the brakes in stopping the train is transferred as heat uniformly to all air in the station, by how much does the temperature rise? The density of air is 1.20 kg/m3 and the specific heat is 1020 J/kg-K.
