Common-Core Grade 7 - 7 Effects of particle motion on gas pressure
|
More particles in a container increase frequency and force collisions.
When particles move more rapidly, they collide with the walls of their container more frequently and with more force.
In a gas, the particles are not closely packed together, so they have more freedom to move around.
When particles collide with the walls of their container more frequently, they exert a greater force on the walls.
More particles in a container force collisions and increase their frequency.
Faster particle motion leads to more collisions.
An increase in temperature causes particles to move more rapidly,which leads to more frequent and forceful collisions.
The rate of diffusion of particles in a gas increases with an increase in temperature, as the particles gain more kinetic energy and move faster.
When particles move more rapidly, they collide with the walls of their container more frequently.
An increase in particle velocity causes more frequent, forceful collisions and raises pressure within the container.
