What happens when a substance is heated?
What happens when a substance is heated?
- The atoms/molecules themselves expand in size.
- The atoms/molecules move faster and the volume of the substance increases. (correct)
- Energy is transferred from the substance and its temperature decreases.
- The atoms/molecules move slower and the volume of the substance decreases.
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)
- Temperature is not related to the speed of atoms/molecules.
- The slower the atoms/molecules move, the higher the temperature.
- The faster the atoms/molecules move, the lower the temperature.
What happens when a substance is cooled?
What happens when a substance is cooled?
- The atoms/molecules themselves shrink in size.
- Energy is transferred to the substance and its temperature increases.
- The atoms/molecules move slower and the volume of the substance decreases. (correct)
- The atoms/molecules move faster and the volume of the substance increases.
