A mercury thermometer has a bulb of volume 0.100 cm3 at 10eC. The capillary tube above the bulb has a cross-sectional area of 0.012 mm2. The volume thermal expansion coefficient of mercury is 1.8 ˛ 10-4 (Ce)-1. How much will the mercury rise when the temperature rises bye C?

The zeroth law of thermodynamics:  If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

Boyle's law: The volume of a gas is inversely proportional to the absolute pressure applied to it when the temperature is kept constant.
Charles's law: The volume of a given amount of gas is directly proportional to the absolute temperature when the pressure is kept constant.
Gay-Lassac's law: At constant volume, the absolute pressure of a gas is directly proportional to the absolute temperature.
