What is the equation derived from Gay-Lussac's Law?

The equation derived from Gay-Lussac's Law is focused on the relationship between pressure and temperature of a gas when volume is held constant. Gay-Lussac's Law states that the pressure of a gas is directly proportional to its absolute temperature when the volume is unchanged.

The correct equation illustrates that as the temperature of a gas increases, the pressure also increases, provided that the amount of gas and its volume remain constant. The form of the equation (P1 \times T2 = P2 \times T1) demonstrates the proportionality and allows for calculations of pressure and temperature changes in a system.

This relationship is critical in many applications, including medical scenarios where understanding gas laws is essential for managing ventilators and other equipment that rely on gas behavior. The way the equation is set up ensures that when rearranged, it can easily help determine any one variable (pressure or temperature) if the other is known, which is particularly useful in flight paramedic settings where quick decisions and calculations are necessary.
