5 Questions
What happens when a substance is heated?
Energy is transferred to the substance, causing the atoms/molecules to move faster and the volume to increase.
What is the relationship between the speed of atoms/molecules and temperature?
The faster the atoms/molecules move, the higher the temperature.
What happens to the volume of a substance when it is cooled?
The volume decreases as the atoms/molecules move closer together.
How do the collisions between atoms/molecules change when a substance is warmed?
The collisions become stronger and more frequent.
What happens to the atoms/molecules themselves when a substance is heated or cooled?
The atoms/molecules do not change in size, only their spacing changes.
Learn about the transfer of energy through heating and cooling processes and how it affects the speed of atoms/molecules, resulting in changes in temperature. Explore how temperature is linked to the average speed of particles.
