11 Questions
When a substance is heated, energy is transferred from the substance.
False
A higher temperature indicates that atoms/molecules are moving slower.
False
Cooling a substance results in the atoms/molecules moving faster.
False
When a substance is warmed, the volume of the substance decreases.
False
When particles move slower, it results in a higher temperature.
False
What happens to the speed of atoms/molecules when a substance is heated?
They gain energy and move faster
How does cooling a substance affect the frequency of collisions between atoms/molecules?
The collisions become weaker and less frequent
What happens to the volume of a substance when it is cooled?
It compresses
Which statement is true about temperature and particle speed?
Particles move slower at lower temperatures
When a substance is warmed, what happens to the collisions between atoms/molecules?
They become stronger and more frequent
What occurs when a substance loses energy as it is cooled?
The atoms/molecules get closer together and compress
Test your knowledge on how energy is transferred when heating or cooling a substance, and how it affects the speed of atoms and molecules which results in a change in temperature. Understand the relationship between temperature and the average speed of particles.
