According to Boyle’s law, we would have to double the pressure to halve the volume. Thus, if the volume of gas is to remain the same, doubling the temperature will require doubling the pressure.This law was first stated by the Frenchman Joseph Gay-Lussac (1778 to 1850). According to Gay-Lussac’s law, for a given amount of gas held at constant volume, the pressure is proportional to the absolute temperature. Mathematically,

where kG is the appropriate proportionality constant.
Gay-Lussac’s law tells us that it may be dangerous to Energy transferred as a result of a temperature difference; a form of energy stored in the movement of atomic-sized particles.

The increased pressure might cause the container to explode.

EXAMPLE 1 A container is designed to hold a pressure of 2.5 atm. The volume of the container is 20.0 cm3, and it is filled with air at room temperature (20°C) and normal atmospheric pressure. Would it be safe to throw the container into a fire where temperatures of 600°C would be reached?
