Questions and Answers
What happens when a substance is heated?
What happens when a substance is heated?
- Energy is transferred to the substance, causing the atoms/molecules to move faster and the volume to increase. (correct)
- Energy is transferred from the substance, causing the atoms/molecules to move slower and the volume to decrease.
- The atoms/molecules expand, causing the volume to increase.
- The atoms/molecules themselves shrink in size, causing the volume to decrease.
How is temperature related to the speed of atoms/molecules in a substance?
How is temperature related to the speed of atoms/molecules in a substance?
- Temperature is a measurement of the total energy of the atoms/molecules.
- Temperature is not related to the speed of atoms/molecules.
- Temperature is a measurement of the average speed of atoms/molecules. (correct)
- Temperature is a measurement of the distance between atoms/molecules.
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 as the atoms/molecules move further apart.
- The volume increases as the atoms/molecules move closer together.
- The volume remains the same as the atoms/molecules do not change their spacing.
- The volume decreases as the atoms/molecules move closer together. (correct)
