Question

At 25°C and 1 atm, a cylinder containing 10 L of an ideal gas is connected to the empty cylinder with a capacity of 20 L. The pressures exerted by gas m both the cylinders will be ____________.

Options

• 2 atm

• 1 atm

• 1.5 atm

• 0.5 atm

Answer 1

At 25°C and 1 atm, a cylinder containing 10 L of an ideal gas is connected to the empty cylinder with a capacity of 20 L. The pressures exerted by gas m both the cylinders will be 0.5 atm.

Explanation:

P₁V₁ = P₂V₂

P₂ = `("P"_1"V"_1)/("V"_2) = (1  "atm" xx 10  "L")/(20  "L")` = 0.5 atm
