A mercury-in-glass thermometer reads -20º at the ice point and 100º at the steam point. Calculate the Celsius temperature corresponding to 70º on the thermometer.

A brass rod is 2 m long at a certain temperature. Calculate the linear expansion of the rod for a temperature change of 100 K. (Take linear expansivity of brass as 1.8 × 10\(^{-5}\) K\(^{-1}\))

An air bubble of volume 2 cm\(^3\) is formed 20 m under water. What will be its volume when it rises to just below the surface of the water if the atmospheric pressure is equivalent to a height of 10 m of water?

The pressure of a given mass of gas changes from 200 Nm\(^{-2}\) to 100 Nm\(^{-2}\), while its temperature drops from 127°C to -73°C. Calculate the ratio of the final volume of the gas to its initial volume.

The temperature of a glass vessel containing 100 cm\(^3\) of mercury is raised from 10°C to 100°C. Calculate the apparent cubic expansion of the mercury. (Real cubic expansivity of mercury = 1.8 × 10\(^{-4}\) K\(^{-1}\), Cubic expansivity of glass = 2.4 × 10\(^{-5}\) K\(^{-1}\))
