Mercury thermometers have been phased out because of the toxicity of mercury vapour. A common replacement for mercury in glass thermometers is the organic liquid, which boils at 182 degrees Celsius. What is its boiling point in degrees Fahrenheit scale? Please include the correct unit symbol with the answer.

Large helium-filled balloons are used to lift scientific equipment to high altitudes. What is the pressure inside such a balloon (in atm) if it starts out at sea level with a temperature of 20.8°C and rises to an altitude where its volume is sixteen times the original volume and its temperature is  −35.7°C?  (Enter your answer to at least 3 decimal places) What is the gauge pressure? (Enter your answer in atm and to at least 3 decimal places. Assume atmospheric pressure is constant.)

An aluminum-alloy rod has a length of 9.8216 cm at 15.00°C and a length of 9.8602 cm at the boiling point of water. (a) What is the length of the rod at the freezing point of water? (b) What is the temperature if the length of the rod is 9.8310 cm? (a) Number Units (b) Number i Units

A cylindrical glass flask with a diameter of 8 cm and the height of 20 cm is fully filled with water at 20°C. When the temperature of the water (and consequently the inner surface of the flask) is raised to 100° C, determine the volume of the water that overflows? HINT 1: Don't forget to calculate the initial volume of the water and flask HINT 2: The volume expansion coefficient for ordinary glass and water can be found in the table of Week 4 (Slide #20). HINT 3: Calculate the volume expansions for both water and the flask HINT 4: The difference between the final volume of water and the final volume of the flask is the amount of overflow.
