Question

For an ideal gas, at constant temperature and pressure, the volume is ____________.

Options

• inversely proportional to the quantity of a gas

• directly proportional to the quantity of a gas

• independent of the quantity of gas

• directly proportional to the square root of the quantity of a gas

Answer 1

For an ideal gas, at constant temperature and pressure, the volume is directly proportional to the quantity of a gas.

Explanation:

PV = nRT

∴ V = `("nRT")/"P"`

∴ `"V" ∝ "n"` ........(∵ R, T, P = constant)
