5 Questions
What happens when a substance is heated?
The atoms/molecules move faster and the volume of the substance increases
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, causing the volume to decrease
What is the effect of heating or cooling on the atoms/molecules themselves?
The atoms/molecules do not expand or shrink, only the volume of the substance changes
How does the frequency and strength of collisions between atoms/molecules change when a substance is heated or cooled?
Heating increases the frequency and strength of collisions, while cooling decreases them
Learn about the concepts of heat transfer and temperature, and how energy is gained or lost when a substance is heated or cooled. Understand how the speed of atoms and molecules is related to temperature.
