**Problem Statement:**A sample of methane gas (CH₄) at 15.7°C is either heated or cooled. The pressure increases from 1.29 atm to 3.87 atm, and the volume of the sample changes from 4.89 L to 4.91 L. To what temperature, in °C, was the methane heated or cooled?**Answer:**[Provide Calculation and Final Temperature Here]**Explanation:**To solve this problem, you can use the combined gas law, which relates pressure (P), volume (V), and temperature (T) of a gas:\[ \frac{P_1 \cdot V_1}{T_1} = \frac{P_2 \cdot V_2}{T_2} \]Where:- \(P_1 = 1.29\) atm- \(V_1 = 4.89\) L- \(T_1 = 15.7 + 273.15\) K (convert Celsius to Kelvin)- \(P_2 = 3.87\) atm- \(V_2 = 4.91\) L- \(T_2 = ?\) K (the temperature you need to find)Rearrange the equation to solve for \(T_2\) and convert the final temperature back to Celsius by subtracting 273.15.
