Multiple Choice
Consider 4.20 L of a gas at 365 mmHg and 20°C. If the container is compressed to 3.00 L and the temperature is increased to 36°C, what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside.

Verified step by step guidance1
Identify the law being discussed: Boyle's Law, which describes the relationship between pressure and volume of a gas at constant temperature.
Recall the statement of Boyle's Law: At constant temperature, the pressure of a gas is inversely proportional to its volume.
Express Boyle's Law mathematically: \( P \propto \frac{1}{V} \) or \( PV = k \), where \( P \) is pressure, \( V \) is volume, and \( k \) is a constant.
Analyze the given options to determine which one aligns with the inverse relationship described by Boyle's Law.
Select the option that states: 'Pressure and volume are inversely proportional at constant temperature,' as it correctly describes Boyle's Law.
