15 Questions
What happens to the speed of atoms/molecules when a substance is heated?
The speed of atoms/molecules increases
How is temperature related to the motion of atoms/molecules?
Temperature is a measure of 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 collisions between atoms/molecules when a substance is warmed?
The collisions become stronger and more frequent
Which of the following statements is true about the atoms/molecules themselves?
The atoms/molecules themselves do not expand or shrink
What is the relationship between energy transfer and the temperature of a substance?
When energy is transferred to a substance, its temperature increases.
What happens to the volume of a substance when it is heated?
The volume increases as the atoms/molecules spread further apart.
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?
The collisions become weaker and less frequent.
What is the process called when a gas transitions to a liquid state?
Condensation
What is the effect of cooling a substance on the atoms/molecules?
The atoms/molecules lose energy and move slower.
What happens to the volume of a substance when it is cooled?
The volume decreases as the atoms/molecules get closer together.
What is the relationship between the speed of atoms/molecules and the strength and frequency of their collisions?
Faster moving atoms/molecules have stronger and more frequent collisions.
What happens to the atoms/molecules themselves when a substance is heated or cooled?
The atoms/molecules do not expand or shrink in size.
How does the formation of water droplets on a cold drink relate to the concept of condensation?
The water droplets form due to the gas molecules in the air transitioning to a liquid state.
