5 Questions
What happens when a substance is heated?
The atoms/molecules gain energy and move faster, resulting in stronger and more frequent collisions.
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?
The atoms/molecules lose energy and move slower, resulting in weaker and less frequent collisions.
What is the relationship between temperature and the volume of a substance?
As temperature increases, the volume of the substance also increases.
What is the main mechanism by which temperature changes in a substance?
Energy is transferred to or from the substance, causing the atoms/molecules to move at different speeds.
Test your knowledge on the transfer of energy through heating and cooling of substances. Learn about how changes in temperature affect the speed of atoms and molecules in a substance.
