What happens to the speed of atoms/molecules when a substance is heated?
- The atoms/molecules move faster (correct)
- The atoms/molecules move slower
- The atoms/molecules stop moving
- The atoms/molecules move at the same speed
What is the relationship between temperature and the speed of atoms/molecules?
What is the relationship between temperature and the speed of atoms/molecules?
- Temperature is a measurement of the average speed of atoms/molecules (correct)
- The slower the atoms/molecules move, the higher the temperature
- Temperature is not related to the speed of atoms/molecules
- The faster the atoms/molecules move, the lower the temperature
