What happens when a substance is heated?
What happens when a substance is heated?
- Energy is transferred from the substance, and the atoms/molecules move slower.
- The atoms/molecules themselves expand in size.
- Energy is transferred to the substance, and the atoms/molecules move faster. (correct)
- The volume of the substance decreases as the atoms/molecules get closer together.
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 a measurement of the volume of the substance.
- Temperature is a measurement of the distance between atoms/molecules.
- Temperature is a measurement of the strength of the collisions between atoms/molecules.
What happens when a substance is cooled?
What happens when a substance is cooled?
- The atoms/molecules themselves shrink in size.
- The atoms/molecules spread further apart, and the volume of the substance increases.
- Energy is transferred from the substance, and the atoms/molecules move slower. (correct)
- Energy is transferred to the substance, and the atoms/molecules move faster.
