What happens when a substance is heated?
What happens when a substance is heated?
- Energy is transferred from the substance and its temperature decreases
- The atoms/molecules gain energy and move faster, resulting in stronger and more frequent collisions (correct)
- The atoms/molecules move slower and the volume of the substance decreases
- The atoms/molecules themselves expand in size
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 only related to the volume of the substance
- Temperature is not related to the speed of atoms/molecules
- Temperature is directly proportional to the speed of atoms/molecules (correct)
- Temperature is inversely proportional to the speed of 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 faster
- The volume remains the same as the atoms/molecules do not change in size
- The volume decreases as the atoms/molecules get closer together (correct)
- The volume changes randomly and is not related to cooling
