Original: T₁ = (273 + 140) K = 413 K, V₁ = 5 L
New: T₂ = ? K, V₂ = 0.19 L
For a fixed amount of gas at constant pressure: V₁/T₁ = V₂/T₂
Then, T₂ = T₁ × (V₂/V₁)
New temperature, T₂ = 413 × (0.19/5) = 15.7 K
New: T₂ = ? K, V₂ = 0.19 L
For a fixed amount of gas at constant pressure: V₁/T₁ = V₂/T₂
Then, T₂ = T₁ × (V₂/V₁)
New temperature, T₂ = 413 × (0.19/5) = 15.7 K
