The Behavior of Gases
-
What is pressure?
Because particles move constantly in gases, the particles constantly collide with other particles and their container
In simple terms, pressure is the amount of force applied per unit of area.
In example, gas in a cylinder, can contain up to TRILLIONS of gas particles. How is that even possible you might ask? Well, these particles exert forces on the cylinder each time they strike it.
Temperature and Volume
Pressure and volume changes are just some of the factors that affect gas behavior. Changing the temperature of a gas also affects its behavior, because when there is less temperature,. there is less volume, and when there is higher temperature there is a greater volume. It kind of works like pressure but differs a little bit regarding ther,al energy and space of particles.
Pressure and Volume
What happens to pressure if the volume of a container changes? Well, when there is additional space in a cylinder, the particles have more room to roam freely and they won't hit eachother :) and that means that the pressure also goes down.
If we decrease the volume, on the other hand, the pressure will SKYROCKET!!! And the temperature might even go up as tested on our Gas Laws simulation and also applying iot to Boyle and Charles' Law.
Charles's Law
A French scientist, Jacque Charles, described the relationship between temperature and a volume of a gas. This law states that the volume of a gas increases with increasing temperature. If the pressure is constant.
Charles's experiences leading up to this discovery: he and his colleague were the first to pilot and FLY a hydrogen-filled BALLOON in 1783!
Charles' law explains much of what we see in the modern world. You've probably seen this old law in action if you have ever taken a balloon outside on a cold winter day. The relationship goes together perfectly! If you think about it, when the balloon is in cold air, the temperature of the has inside the balloon decreases, meaning a decrease in the average kinetic energy of particles in the space.
When graphing Charles's Law, temperature goes on the x-axis and volume on the y-axis.
Boyle's Law
Robert Boyle is a British scientist who was the first to describe property of gases. Basically, his law states that the pressure of a gas increases if the colme decreases and pressure of a has decreases if the volume increases, when temperature is constant.
Boyle's action comes into our lives, on an airplane! While on the ground, the air pressure inside your middle ear AND the pressure of the air surrounding you are equal. As the airplane takes off and begins to increase in altitude. the air pressure of the surrounding air decreases.
