Question

question 3 of 10
boyles law of gases, states that.....
the pressure of a gas increases as the volume of its container increases.
the volume of a gas will decrease as the pressure on the gas decreases.
the volume of a gas and the pressure of a gas are directly proportional.
the volume of a gas and the pressure of a gas are inversely proportional.

Explanation:

Boyle's law states that for a given mass of gas at a constant temperature, \( P_1V_1 = P_2V_2\), which means \( P\propto\frac{1}{V}\) (pressure \(P\) and volume \(V\) are inversely proportional).

• The first option is wrong because when volume increases, pressure should decrease (not increase) according to Boyle's law.
• The second option is wrong. When pressure decreases, volume should increase (not decrease) as per \(P\propto\frac{1}{V}\).
• The third option is wrong. Direct proportionality (\(P\propto V\)) is not what Boyle's law states. Boyle's law is about inverse proportionality.

Answer:

the volume of a gas and the pressure of a gas are inversely proportional.
