Explanation:
To answer this question we'll use Charles' law, which relates the temperature and volume of a gas at constant pressure:
V₁T₂=V₂T₁
Now we convert the given temperatures to K:
T₁ = 135 °C ⇒ 135 + 273.16 = 408.16 KT₂ = 15 °C ⇒ 15 + 273.16 = 288.16 KAnd given that V₁ = 45 mL, we can input the data:
45 mL * 288.16 K = V₂ * 408.16 KAnd solve for V₂:
V₂ = 32 mL
