10 Questions
What happens when a substance is heated?
The atoms/molecules gain energy and move faster
How is temperature related to the motion of atoms/molecules?
Temperature is a measure of the average speed of atoms/molecules
What happens to the volume of a substance when it is cooled?
The volume decreases as the atoms/molecules get closer together
Which of the following statements is true about the atoms/molecules themselves during heating or cooling?
The atoms/molecules remain the same size during heating and cooling
What happens to the collisions between atoms/molecules when a substance is heated?
The collisions become stronger and more frequent
What is the main difference between evaporation and boiling?
Evaporation only happens on the surface, while boiling occurs throughout the liquid.
Why does the drop of rubbing alcohol evaporate faster on your hand than on the table?
Due to the difference in the temperature of your hand and the table.
What role do air particles play in the process of evaporation?
Air particles provide energy to liquid molecules at the surface, aiding in their escape.
What effect does an increase in temperature have on the rate of evaporation?
Higher temperatures speed up evaporation.
At what point does a liquid reach its boiling point?
When all molecules in the liquid have turned into a gas.
