Term 4- Kinetic Theory of Gases Flashcards
Gases are composed of particles such as ____________ or _____________
Gases are composed of particles such as ATOMS or MOLECULES
The gases particles are a _______ _______ ________ of the gas particles when compared to the volume of the container
The gases particles are a VERY SMALL SUM of the gas particles when compared to the volume of the container
The gas particles move very _____, travelling in ______ lines, until they collide with the _______ walls or other _________
The gas particles move very QUICKLY, travelling in STRAIGHT lines, until they collide with the CONTAINER walls or other PARTICLES
The forces of attraction between particles are extremely_____________
The forces of attraction between particles are extremely WEAK
Collisions are perfectly __________
Collisions are perfectly ELASTIC
As the temperature for the gas is raised, the average kinetic energy of the particles _______
As the temperature of the gas is raised, the average kinetic energy of the particles INCREASES
Explain. Liquid water cannot be compressed easily but a sample of stem can
Liquids- more tightly packed
Particle of steam- large spaces between them
Therefore steam can be compressed
The smell of an aerosol sprayed in one corner of a room will quickly spread through the room
Gas Particles move rapidly and because of the spaces between them, the aerosol is able to diffuse throughout the room
An increase in volume of a gas causes a decrease in pressure
Pressure is exerted by gas particles colliding with the container walls. If you increase the volume, the pressure is decreased because there is a larger space to collide with
An increase in temperature in a gas filled balloon leads to an increase in the size of the balloon.
As the temperature increases, the gas particles gain kinetic energy and move faster on the walls of the walls. The pressure remains constant so the volume of the balloon is increased
A gas fills any container into which it is put and exerts pressure on the walls of the container
Gas particles move randomly in the container they are placed as they have no fixed volume. Pressure is exerted when the gas particles hit the container walls.
The pressure of a gas rises if it is heated in a vessel of a fixed volume
As the temperature rises gas particles gain kinetic energy and move faster. As they move faster more collisions occur with the container walls. This increase in collisions results in increased pressure
If a balloon is placed in a bucket of iced water, its volume is less than if the same balloon is placed in a bucket of hot water. Explain why this happens and what gas law is demonstrated
In iced water, the particles have less kinetic energy and don’t move as much. To keep the pressure constant, the volume decreases
When the particles are heated, they have more kinetic energy and more faster. To keep the pressure constant, the volume increases.
This demonstrates Charles Law
Charles Law
V1/T1 = V2/T2
Boyles Law
P1V2 = P2V2
