This lesson told us all about pressure, which can be defined simply as the force with which particles in a sample of gas hit the sides of their container. Pressure is related to temperature and volume through the use of three laws: Boyle's, Charles's, and Gay-Lussac's. There exists a thing called atmospheric pressure, or atm, which is pressure that constantly weighs on everything on a planet's surface. Earth's typical atm is around 14.7 and can increase/decrease when you're at sea level or on top of a mountain.

Lesson 10:
You can use Boyle's law to help calculate varying pressures when volume is constant. When volume doesn't change, it's greatly possible that a gas sample is in a rigid container, or one that doesn't change size/shape, like a graduated cylinder, a bowl, box, or a beaker. The following equation represents Boyle's law:
k = PxV
where k is your proportionality constant, or a value that stays the same in all calculations using Boyle's law. With this equation, you know that pressure and volume are indirectly proportional. When pressure increases, volume decreases, and vice versa.
