What happens when a substance is heated?
What happens when a substance is heated?
- The atoms/molecules expand and shrink
- The atoms/molecules gain energy and move faster (correct)
- The atoms/molecules stay the same speed
- The atoms/molecules lose energy and move slower
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 total speed of atoms/molecules
- Temperature is a measurement of the maximum speed of atoms/molecules
- Temperature is unrelated to the speed of atoms/molecules
- Temperature is a measurement of the average speed of atoms/molecules (correct)
What happens to the volume of a substance when it is cooled?
What happens to the volume of a substance when it is cooled?
- The volume increases
- The volume decreases (correct)
- The volume first increases then decreases
- The volume stays the same
