12 Questions
What happens when a substance is heated?
Energy is transferred to the substance, causing the atoms/molecules to move faster.
When the atoms/molecules in a substance move faster, what happens to the temperature?
The temperature increases.
What happens to the volume of a substance when it is cooled?
The volume decreases due to the atoms/molecules contracting.
What happens to the collisions between atoms/molecules when a substance is heated?
The collisions become stronger and more frequent.
Which of the following statements is true about the atoms/molecules themselves when a substance is heated or cooled?
They remain the same size, but move faster when heated and slower when cooled.
What is the relationship between the speed of atoms/molecules and temperature?
The faster the atoms/molecules move, the higher the temperature.
What happens to the collisions between atoms/molecules when a substance is cooled?
Collisions become weaker and less frequent
How does cooling a substance affect the volume of the substance?
It decreases the volume
What factor determines the temperature of a substance?
Average speed of the atoms/molecules
How does warming a substance affect the frequency of collisions between atoms/molecules?
Frequency increases
What happens to a substance when its atoms/molecules move slower?
Temperature decreases
What is the result of atoms/molecules getting closer together in a substance?
The volume of the substance decreases
