Step 1

15 L and the initial pressure (P1) is 1.00 atm. We are also given that the final volume of the gas (V2) is 9.25 L. We are asked to find the final pressure (P2) of the gas. Show more…

Key Concepts

Boyle's Law

Boyle's Law is a fundamental gas law which states that for a fixed amount of gas at a constant temperature, the pressure and volume are inversely proportional. This means that when the volume of the gas increases, its pressure decreases proportionally, and vice versa.

Pressure Unit Conversion

Pressure unit conversion is important when solving problems that involve different units of pressure measurement. For example, converting pressure from atmospheres (atm) to millimeters of mercury (mmHg) uses the conversion factor 1 atm = 760 mmHg, ensuring consistency and correctness in calculations.

Inverse Proportionality

Inverse proportionality describes a relationship between two variables where the product of the variables remains constant. In the context of gas laws, it is applied to understand that as the volume of a gas increases, its pressure decreases by the same factor, under constant temperature conditions.
