If the gas is cooled at constant pressure to a temperature of 7 °C, the volume of the gas sample will be
L.

Original: V₁ = 7.68 L, T₁ = (273 + 30) K = 303 K
New: V₂ = ? L, T₂ = (273 + 7) K = 280 K
For a fixed amount of gas under constant pressure: V₁/T₁ = V₂/T₂
Then, V₂ = V₁ × (T₂/T₁)
New volume, V₂ = 7.68 × (280/303) L = 7.10 L
New: V₂ = ? L, T₂ = (273 + 7) K = 280 K
For a fixed amount of gas under constant pressure: V₁/T₁ = V₂/T₂
Then, V₂ = V₁ × (T₂/T₁)
New volume, V₂ = 7.68 × (280/303) L = 7.10 L

(7.68 L) x (7 + 273) K / (30 + 273) K = 7.10 L
