12 Questions
What happens to the speed of atoms/molecules when a substance is heated?
The speed of atoms/molecules increases.
What is the relationship between temperature and the average speed of atoms/molecules?
Temperature is directly proportional to the average speed of atoms/molecules.
What happens to the volume of a substance when it is cooled?
The volume of the substance decreases.
What happens to the frequency and strength of collisions between atoms/molecules when a substance is warmed?
The frequency and strength of collisions increase.
What happens to the atoms/molecules themselves when a substance is heated or cooled?
The atoms/molecules remain the same size regardless of temperature changes.
What is the relationship between energy transfer and temperature change in a substance?
Energy transfer to a substance results in an increase in temperature.
What happens to the volume of a substance when it is cooled?
It decreases as the atoms/molecules get closer together.
What is the impact on collisions between atoms/molecules when a substance is cooled?
Collisions become weaker and less frequent.
What happens to the speed of atoms/molecules when a substance is heated?
Speed increases as energy is transferred to the substance.
How does increased energy transfer affect the temperature of a substance?
Temperature increases with increased energy transfer.
What causes a substance to expand and increase in volume?
Atoms/molecules spreading further apart
When a substance is cooled, why do atoms/molecules get closer together?
Loss of energy and slower movement
