What happens to particles when they are evenly dispersed throughout a space?
they start moving towards areas of high concentration
they stop moving
they start moving in a regular pattern
they continue to move randomly
|
How does an increase in temperature affect particle movement?
particles move quicker and collide more forcefully
particles start moving in a regular pattern
particles move slower and collide less forcefully
particle movement is not affected by temperature
|
What happens to the pressure in a container when the temperature increases?
the pressure remains the same
the pressure decreases
the pressure increases
|
What causes the increase in pressure in a container when the temperature rises?
increased particle collision with container walls
decreased particle collision with container walls
decreased particle size
increased particle size
|
What is the main cause of particle movement in Brownian motion?
electric charges
gravity
magnetic forces
collisions between particles
|
What is the term for the movement of particles from areas of high concentration to areas of low concentration?
diffusion
expansion
contraction
brownian motion
|
At higher temperatures, particles have more energy, so they move quicker and collide more forcefully.
|

|
Explain the effects of increasing temperature on particle movement.
