Final answer:
Charles's Law can be used to find the volume change caused by a temperature change at constant pressure. By using the equation V₁/T₁ = V₂/T₂ and converting the temperature into Kelvin, we can solve for the new volume and temperature.
Step-by-step explanation:
When a temperature change occurs at constant pressure, we can use Charles's Law to find the volume change. Charles's Law states that the volume of a gas is directly proportional to its temperature, as long as pressure and amount of gas remain constant. By converting the temperature from Celsius to Kelvin and using the initial volume and temperature as V₁ and T₁, and the unknown volume and temperature as V₂ and T₂, we can use the equation V₁/T₁ = V₂/T₂ to solve for the new volume and temperature.
