Answer:
V₂ = 379.80 mL
Explanation:
According to Charles' Law, "At constant pressure the volume of given amount of gas is directly proportional to the absolute temperature". Mathematically it is given as,
V₁ / T₁ = V₂ / T₂ ----- (1)
Data Given:
V₁ = 185 mL
T₁ = -125 °C = 148.15 K ∴ K = °C + 273.15
V₂ = ?
T₂ = 31.0 °C = 304.15 K
Solving eq. 1 for V₂,
V₂ = V₁ × T₂ / T₁
Putting values,
V₂ = 185 mL × 304.15 K / 148.15 K
V₂ = 379.80 mL
Hence, with increase in temperature the volume has also increased.
