The thermometric property of a mercury thermometer is the expanded volume of mercury.

It can be measured the expanded volume of mercury for temperature at 5C is 3 cm3, and 5 cm3 for temperature at 30C. We use this thermometer for measuring the temperature of air and water in the room.

a. Sketch the graph of pressure and absolute temperature for this thermometer.

b. If the volume of mercury is expanded 6 cm3, what is temperature of air?

c. If we use this thermometer measure the temperature of water, what is the

different volume of mercury at the boiling point and melting point of water?
