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 less frequent collisions
How do the atoms/molecules themselves change when a substance is heated or cooled?
The atoms/molecules do not expand or shrink, only their speed changes
What is the relationship between energy transfer and temperature change?
Heating a substance means energy is transferred to it, and cooling means energy is transferred from it
Test your knowledge on heat transfer, energy gain/loss, and temperature changes in substances. Learn about the relationship between energy transfer and the speed of atoms/molecules.
