A A sample of krypton gas at a pressure of 905 torr and a temperature of $28.4^{\circ} \mathrm{C}$ occupies a volume of $631 \mathrm{mI}$.. If the gas is allowed to expand at constant temperature until its pressure is 606 torr, what will be the volume of the gas sample (in liters)?

Key Concepts

Boyle's Law

Boyle's Law is a fundamental gas law which states that, for a fixed amount of gas at constant temperature, the pressure and volume are inversely proportional to each other. This means that if the pressure on the gas decreases, the volume increases proportionally, and vice versa, allowing one to calculate the new volume or pressure when the other changes under isothermal conditions.

Isothermal Process

An isothermal process refers to a physical process during which the temperature of the system remains constant. In the context of gases, this means that the kinetic energy of the particles stays constant, and any change in pressure or volume is strictly a consequence of their inverse relationship according to Boyle's Law.

Unit Conversion

Unit conversion is a critical concept in applying gas laws accurately. It involves converting quantities such as pressure (e.g., torr to atmospheres) or volume (e.g., milliliters to liters) into consistent units, which ensures the formulas used, like Boyle's Law, work correctly without unit discrepancies.

Ideal Gas Behavior

Ideal gas behavior is the assumption that a gas's molecules do not interact and occupy no volume, which simplifies the mathematical treatment of gas properties. This model is useful for approximating the behavior of real gases under many conditions, allowing the use of laws such as Boyle's Law to predict changes in state variables like pressure and volume.
