🔍 Key Concepts

• Boyle's Law (pressure–volume relationship at constant temperature) • Difference between directly proportional and inversely proportional • How gas volume changes when pressure increases while temperature is unchanged

💭 Think About

• Ask yourself: When temperature is held constant and you squeeze a gas into a smaller space, what happens to the pressure? • Think: In Boyle’s Law, if you double the pressure on a gas (with temperature constant), what happens to the volume? • Identify which choices are talking about constant temperature (Boyle’s Law) versus constant pressure (another gas law).

✅ Before You Answer

• Make sure the option you pick involves constant temperature, not constant pressure. • Check whether the relationship described is inverse (one goes up, the other goes down) or direct (both go up together). • Eliminate the choices that clearly describe a different gas law dealing with constant pressure instead of constant temperature.
