12 Questions
What happens when a substance is heated?
The atoms/molecules gain energy and move faster
What is temperature a measurement of?
The average speed of the atoms/molecules
What happens when a substance is cooled?
The atoms/molecules lose energy and move slower
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 heated?
The volume increases as the atoms/molecules spread further apart
What happens to the collisions between atoms/molecules when a substance is warmed?
The collisions become stronger and more frequent
Which of the following is NOT a consequence of cooling a substance?
The atoms/molecules themselves shrink in size.
How does the average speed of atoms/molecules relate to the temperature of a substance?
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.
Which of the following is a consequence of heating a substance?
The atoms/molecules gain energy and move faster.
What is the relationship between the temperature of a substance and the energy of its atoms/molecules?
Higher temperature means the atoms/molecules have more energy.
What is the main effect of cooling a substance on the collisions between its atoms/molecules?
The collisions become weaker and less frequent.
