Gas Laws - Boyle's Law

Vocabulary and key concepts from the lecture notes on Gas Laws, focusing specifically on Boyle's Law and its mathematical relationships.

Three Quantities of Gas Behavior

The three quantities used to study the behavior of gases: 1. Pressure, 2. Volume, and 3. Temperature.

Boyle's Law

A gas law that relates the relationship between the pressure and volume of a gas at a constant temperature.

Inversely Proportional

The relationship in Boyle's Law stating that the volume of a fixed mass of gas decreases as pressure increases, provided temperature is held constant.

$$P \propto \frac{1}{V}$$

The mathematical proportionality showing that pressure is inversely proportional to volume.

$$PV = \text{Constant}$$

The equation representing that the product of pressure and volume remains constant in Boyle's Law, often written as $P_1V_1 = P_2V_2$.

Constant Variables in Boyle's Law

The two factors that must remain unchanged for Boyle's law to apply: Temperature and a fixed mass of gas.

$$Pa$$

The unit of pressure (Pascal) used in the example calculation, such as $1 \times 10^5\,Pa$.

$$cm^3$$

The unit of volume used in the example calculation, such as $30\,cm^3$.
