Final answer:
To solve problems using Charles's Law, you would use the equation V₁/T₁ = V₂/T₂ and substitute the given values to find the unknown volume or temperature.
Step-by-step explanation:
Charles's Law can be used to compare changing conditions for a gas. It states that when the volume of a gas changes due to a temperature change at constant pressure, the ratio of the initial volume and temperature (V₁/T₁) is equal to the ratio of the final volume and temperature (V₂/T₂).
The mathematical equation that represents Charles's law is: V₁/T₁ = V₂/T₂. To solve problems using Charles's Law, you would use this equation and substitute the given values for V₁, T₁, and either V₂ or T₂ to find the unknown volume or temperature.
