PS_Particle Movement Pre-quiz warm up

At 6 seconds, which image has a higher temperature based on the particle placement?

• 
• 
• 

At 6 seconds, which image has larger particles based on the particle placement?

• 
• 
• 

At 6 seconds, which image has the smallest particles based on the particle placement?

• 
• 
• 

3 different phases exist at the same temperature of a particular substance. Which phase would be moving the fastest?

• liquid

• gas

• solid

• it is the same- at the same temperature

This image suggests what?

• the particles in the cylinder to the left is moving faster

• the particles in the cylinder to the right is moving faster

• the cylinder to the left has fewer particles

• the cylinder to the right has fewer particles

What is missing on this diagram?

• a key

• different particles

• arrows indicating movement

• it's perfect just the way it is

Looking at this image, what might the teacher suggest to make it easier to understand?

• to add a key

• to use different colors

• to use fewer particles

• to make arrows length more obviously different

If you want to speed up the dispersion of a particle you should?

• cool it down and make it have a high mass

• cool it down and make it have a small mass

• warm it up and make it have a big mass

• warm it up and make it have a small mass

What error has this student made?

• arrows are too long

• no key provided

• the particle number changes throughout the sequence

• there are no errors

How do particles move in gases and liquids?

• completely random

• organized and with determination

• a straight line

• they are fixed in a rigid shape
