Question

When the pressure of a gas decreases, which quantity will increase, assuming all other variables are held constant?

1. n

2. T

3. R

4. V

Answer 1

The volume(V) of gas will increase when the pressure of the gas decreases assuming all the other variables are held constant.

Explanation:

• The ideal gas equation of an ideal gas is given:

             $PV=nRT$

Where:

            P = Pressure of the ideal gas

             V = Volume of the ideal gas

             n = Moles of the ideal gas

             R = Universal gas constant

             T = Temperature of the ideal gas

On rearranging the above equation:

$P=\frac{nRT}{V}$

From this expression, we can deduce to things:

• The pressure of the ideal gas is directly proportional to the moles of the ideal gas and the temperature of the ideal gas.

                 $P\propto (nT)$

• The pressure of the ideal gas is inversely proportional to the volume of the ideal gas.

                 $P\propto \frac{1}{V}$

So, from this, we can conclude that volume(V) of gas will increase when the pressure of the gas decreases assuming all the other variables are held constant.
