Solids, Liquids, and Gases (Lesson 3, Gas Behavior) Flashcards
What happens when the temperature of a gas at a constant volume is increased?
The pressure of the gas increases because the gas particles will collide with the wall of their container with greater force.
What happens when the temperature of a gas at a constant volume is decreased?
The pressure of the gas decreases because the gas particles will collide with the wall of their container with less force.
Why do the tires of big trucks burst sometimes on very hot days?
As the temperature increases, the pressure of the air inside the tires increases more than what the tires can hold, causing them to burst.
What is Charles’ Law?
When the temperature of a gas at constant pressure is increased, its volume increases. When the temperature of a gas at constant pressure is decreased, its volume decreases.
What does is it mean when two variables are directly proportional?
As one variable increases, the other variable increases.
When shown on a graph, the two variables are a straight line passing through the origin.
What is Boyle’s Law?
When the pressure of a gas at a constant temperature is increased, the volume of the gas decreases. When the pressure of a gas at a constant temperature is decreased, the volume of the gas increases.
How does Boyles Law apply to a bicyle pump?
When you push down increasing the pressure, the volume decreases, and the air is forced into the bike tire.
What does it mean when two variable are inversely proportional?
As one variable increases, the other variable decreases.
When shown on a graph, the two variables form a curve.
