10 Questions
What happens to the atoms/molecules of a substance when it is warmed?
They gain energy and move faster.
How does cooling affect the collisions between atoms/molecules of a substance?
Collisions become weaker and less frequent.
What does temperature measure in terms of atoms/molecules?
Speed of atoms/molecules
What happens to the volume of a substance when it is cooled?
It decreases
How do gaseous atoms/molecules travel before colliding with each other or an object?
In straight lines
What is the main cause of a change in temperature?
The transfer of energy to or from a substance
What happens to the volume of a gas when it is heated?
The volume increases as the atoms/molecules move further apart
How do gaseous atoms/molecules travel when they are not colliding?
They move in straight lines
What is the primary reason for odors being able to travel through the air?
The odor particles travel in all directions
What happens to the strength and frequency of collisions between atoms/molecules when a substance is cooled?
The collisions become weaker and less frequent
