6 Questions
What happens when a substance is heated?
The atoms/molecules gain energy and move faster
What does temperature measure?
The average speed of the atoms/molecules
What happens to the volume of a substance when it is cooled?
The volume decreases as the atoms/molecules get closer together
How are the collisions between atoms/molecules affected when a substance is cooled?
The collisions become weaker and less frequent
What happens to the atoms/molecules themselves when a substance is heated or cooled?
The atoms/molecules do not change in size or shape when heated or cooled
What is the relationship between temperature and the speed of atoms/molecules?
Temperature is directly proportional to the speed of atoms/molecules
Test your knowledge on the concepts of heat transfer and temperature. Learn about how energy is transferred to and from substances, resulting in changes in the speed of atoms and molecules, which are detected as changes in temperature.
