5 Questions
What happens when a substance is cooled?
Atoms/molecules lose energy and move slower
Which statement best describes temperature?
A measurement of the average speed of atoms/molecules
What happens to the volume of a substance when it is warmed?
The atoms/molecules spread further apart (expand) and the volume increases
How does cooling a substance affect the speed of particles?
Particles lose energy and move slower
What is the relationship between heating a substance and the frequency of collisions?
Collisions become stronger and more frequent
Learn how heat transfer affects the speed of particles, temperature changes, and volume variations in a substance. Explore how energy transfer leads to changes in atom/molecule speed, resulting in temperature fluctuations.
