11 Questions
What is the result when energy is transferred to a substance?
The atoms/molecules gain energy and move faster.
What happens to the volume of a substance when it is warmed?
The volume increases as the atoms/molecules spread further apart.
What is the relationship between temperature and the speed of atoms/molecules?
The faster the atoms/molecules move, the higher the temperature.
What happens to the volume of a substance when it is cooled?
The volume decreases as the atoms/molecules get closer together.
What happens to the atoms/molecules themselves when a substance is heated or cooled?
The atoms/molecules do not change in size, only their speed changes.
What happens to the average speed of atoms/molecules when a substance is heated?
It increases
What occurs to the collisions between atoms/molecules when a substance is cooled?
They weaken and become less frequent
What is the relationship between energy transfer and temperature change in a substance?
Directly proportional
How does the volume of a substance change when it is warmed?
It increases
What happens to the volume of a substance when it is cooled?
It decreases
What effect does energy transfer have on the speed of atoms/molecules in a substance?
It changes the speed
