6 Questions
Which of the following statements accurately describes the relationship between molecular motion and temperature?
Faster molecular motion corresponds to higher temperatures.
When a substance is heated, what happens to the volume of the substance?
The volume increases as the atoms/molecules move farther apart.
If the atoms/molecules of a substance are observed to be moving slower, what can be inferred about the temperature of the substance?
The temperature of the substance is decreasing.
Which of the following statements accurately describes the behavior of atoms/molecules when a substance is cooled?
The atoms/molecules lose energy and move slower, resulting in weaker and less frequent collisions.
Which of the following statements is true regarding the size of atoms/molecules during changes in temperature?
The atoms/molecules themselves do not change size, but their spacing changes.
In the context of the provided information, what is the primary cause of the change in volume of a substance when its temperature changes?
The change in the average speed of the atoms/molecules, affecting their spacing.
Test your knowledge on the concepts of temperature, energy transfer, and the speed of atoms and molecules. Learn about how heating and cooling affect the motion of particles and the resulting changes in temperature.
