10 Questions
What happens to the energy when a substance is heated?
Energy is transferred to the substance, it gains energy.
How does cooling a substance affect the energy in the substance?
Energy is transferred from the substance, it loses energy.
What does an increase in temperature indicate about the speed of atoms/molecules?
They move faster.
What happens to the volume of a substance when it is warmed?
It increases.
How do atoms/molecules behave when a substance is cooled?
They get closer together (compress).
Which of the following factors has the greatest effect on the rate of evaporation?
Absolute temperature
How does increasing the temperature affect the evaporation rate?
It increases the evaporation rate exponentially.
What is the primary reason why high humidity reduces the evaporation rate?
It fills the air with water vapor, hindering more evaporated molecules from escaping.
How does increasing the surface area of a liquid affect its evaporation rate?
It increases the evaporation rate linearly.
Which of the following is NOT mentioned in the text as a factor affecting the evaporation rate?
Pressure
