Question

What gas law states that volume and pressure are inversely proportional, while directly proportional to temperature when moles are held constant

Answer 1

Combined gas law states that when the number of moles of an ideal gas are held constant, the volume and pressure of the gas are inversely proportional while being directly proportional to temperature.

Under combined gas law, the three (3) main gas laws are combined together and these include:

• Boyle's law.

• Charles' law.

• Gay-Lussac's law.

Mathematically, the combined gas law is given by the formula:

$\frac{PV}{T} =k\\\\\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}$

Where:

• P is the pressure of a gas.

• T is the temperature of a gas.

• V is the volume of a gas.
