Determine the final length of a copper pipe that is 18m long at 20C when it is heated to 350C. [3 Marks] 4. 10 kg of silver at 500C is dropped into 25kg of water at 15C. What is the final temperature when the system reaches equilibrium? [3 Marks] 5. The radius of a glass rod is 12.0 cm at 90C. Determine the cross-sectional area after it is cooled to 0C. [3 Marks] 6. A compressor takes 3.2 m of an unknown gas at atmospheric pressure and compresses it to 0.7 m at a constant temperature. What is the final pressure of the gas? [3 Marks] 7. How many joules of heat are needed to melt 215 kg of ice at 0C, bring it to a boil, and raise its final temperature to 150C? [4 Marks] 8. An unknown gas is measured at 15C to have a gauge pressure of 80 kPa and its volume is 20 L. If the temperature is raised to 75C and the volume is compressed to 12 L what is the final pressure? [5 Marks] 9. An unknown gas is measured to have a gauge pressure of 70 psi and its volume is 18 L. If the volume is compressed to 6 L with a pressure of 190 psi and an observed temperature of 120C, what was the initial temperature? [5 Marks] 10. (With reference to the Thermal Properties data sheet in the course con- tent) 1 kg of Mercury is heated from -50C to 400C. Sketch the diagram illustrating the relationship between temperature and heat energy, and calculate the total heat required for this process. Be sure to include the phase transitions if/when appropriate. [8 Marks]
