**Understanding Boyle's Law**

Boyle's Law states: "All other things being equal, the pressure of a gas is inversely proportional to its volume."

**Question (a): What is the meaning of the term "inversely proportional?"**

Options provided:

- As the pressure increases, the volume of the gas decreases and vice-versa or \( P \propto V \).
  
- ✅ As the pressure increases, the volume of the gas decreases and vice-versa or \( P \propto \frac{1}{V} \).

- As the pressure increases, the volume of the gas increases and vice-versa or \( P \propto \frac{1}{V} \).

- As the pressure increases, the volume of the gas increases and vice-versa or \( P \propto V \).

The correct answer is the second choice, where pressure and volume are inversely related, meaning as one increases, the other decreases.

**Question (b): What are the "other things" that must be equal? (Select all that apply.)**

Options provided:

- ☑️ Density of the gas

- Proportionality constant

- ☑️ Number of moles

- ☑️ Temperature

This question clarifies that for Boyle's Law to hold, the density of the gas, number of moles, and temperature must remain constant. The correct selections are density, number of moles, and temperature.
