Question

Which law is described by saying that when the pressure of a gas in a sealed container is cut in half, the gas will double in volume at a steady temperature?
Boyle’s law
Charles’s law
Dalton’s law
Gay-Lussac’s law

Answer 1

Answer: The correct answer is Boyle's law.

Explanation:

Boyle's law states that 'the pressure of the gas is inversely proportional to the volume occupied by the gas at constant temperature'.

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

$PV=constant$ or $P_1V_1=P_2V_2$

According to question, pressure is reduced to half of its original value by which volume of gas will get doubled of its initial value.Hence following Boyle's law.

Answer 2

I believe it would be Boyle's Law

(P [is proportional to] 1/V)

P being pressure

V being volume
