Question

A gas is heated from 273 K to 373 K at 1 atm pressure. If the initial volume of the gas is 10 L, its final volume would be ______.

Options

• 20 dm³

• 13.66 dm³

• 10 dm³

• 7.32 dm³

Answer 1

A gas is heated from 273 K to 373 K at 1 atm pressure. If the initial volume of the gas is 10 L, its final volume would be 13.66 dm³.

Explanation:

T₁ = 273 K

T₂ = 373 K

V₁ = 10 L

V₂ = ?

From Charles law,

`"V"_1/"T"_1 = "V"_2/"T"_2`

`"V"_2 = 373 xx 10/273` = 13.66 L = 13.66 dm³
