At constant temperature, the pressure and volume of a gas are ______ proportional.

• inversely

• directly

In all gas laws calculations, temperature must be measured in

• Kelvins (K)

• Celcius (ºC)

• Farenheit (ºF)

Which law describes the relationship between a gas's temperature and volume when its pressure is constant

• Boyle's
• Darwin's
• Newton's
• Charles's

What is Boyle's Law?

• At a constant volume, when the temperature of a gas increases, the pressure increases.
• At a constant volume, when the temperature of a gas increases, the pressure decreases.
• At a constant pressure, when the temperature of a gas increases, the volume decreases.
• At a constant temperature, when the pressure of a gas increases, the volume decreases.
