6 Questions
What happens when a substance is heated?
Energy is transferred to the substance, and the atoms/molecules move faster.
What is the relationship between temperature and the speed of atoms/molecules?
Temperature is a measurement of the average speed of atoms/molecules.
What happens when a substance is cooled?
Energy is transferred from the substance, and the atoms/molecules move slower.
How does the volume of a substance change when it is heated?
The volume increases as the atoms/molecules spread further apart.
How does the frequency and strength of collisions between atoms/molecules change when a substance is heated?
The collisions become more frequent and stronger.
What is the effect of cooling a substance on the distance between its atoms/molecules?
The atoms/molecules get closer together, and the volume of the substance decreases.
