Gas Laws and Martian Adventures

Pressure and volume have an inverse relationship in gases, according to Boyle's Law.

Pressure is the force exerted by gas molecules on the walls of their container.

Volume is usually measured in meters cubed.

<p>Boyle's Law states that at constant temperature, pressure and volume are inversely proportional to each other. When air is removed from the jar, the gas pressure inside decreases, causing the marshmallows to expand due to increased volume.</p> Signup and view all the answers

<p>Charles' Law states that at constant pressure, temperature and volume are directly proportional to each other. When the marshmallow is heated in the microwave, the increased temperature leads to an increase in volume, causing the marshmallow to expand.</p> Signup and view all the answers
