Questions and Answers
What happens when a substance is heated?
What happens when a substance is heated?
- 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.
- Energy is transferred from the substance, and the atoms/molecules move slower.
- The atoms/molecules themselves expand in size.
How does temperature relate to the speed of atoms/molecules?
How does temperature relate to the speed of atoms/molecules?
- Temperature is a measurement of the average speed of atoms/molecules. (correct)
- Temperature is a measurement of the total speed of all atoms/molecules.
- Temperature is not related to the speed of atoms/molecules.
- Temperature is a measurement of the number of atoms/molecules in the substance.
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 decreases as the atoms/molecules get closer together. (correct)
- The volume changes randomly and is not related to the cooling of the substance.
- The volume stays the same as the atoms/molecules do not change in size.
- The volume increases as the atoms/molecules spread further apart.
