Question

If a gas at 25.0 °C occupies 5 liters at a pressure of 1.00 atm, what will be its volume at a pressure of 4 atm?

Answer 1

Answer:

1.25L

Explanation:

Applying Gay-Lussac's Law which states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.

$p_1v_1=p_2v_2\\\\5l\times 1.00atm=4.0atm\tiimes x\\\\x=5/4=1.25L$

Hence the volume at 4.0atm is 1.25L
