12 Questions
What happens to the atoms/molecules when a substance is warmed?
They gain energy and move faster
What happens to the collisions between atoms/molecules when a substance is warmed?
The collisions become stronger and more frequent
What happens to the volume of a substance when it is cooled?
The volume decreases
How do gaseous atoms/molecules travel?
They travel in straight lines until they collide with each other or an object
What is the process called when molecules in the gaseous state slow down and become a liquid?
Condensation
What is the temperature at which molecules throughout a liquid can change to the gaseous state?
The boiling point
What is the difference between evaporation and boiling?
Evaporation happens at any temperature, while boiling requires a specific temperature.
What happens to the speed of atoms/molecules when a substance is heated?
The speed of atoms/molecules increases.
Which of the following statements about temperature is correct?
Temperature is a measure of the average kinetic energy of atoms/molecules.
What happens when energy is transferred from a substance?
The speed of atoms/molecules decreases, and the temperature drops.
Which process involves the gain of energy by a substance?
Heating
What happens to the volume of a substance when it is heated?
The volume increases due to the atoms/molecules moving farther apart.
