10 Questions
What happens to the speed of atoms/molecules when energy is transferred to a substance?
The speed increases
How does cooling a substance affect the volume of the substance?
The volume decreases
What does temperature measure in a substance?
Average speed of atoms/molecules
What happens to the collisions between atoms/molecules when a substance is warmed?
Collisions become stronger and more frequent
What happens to the collisions between atoms/molecules when a substance is cooled?
Collisions become weaker and less frequent
What is the main difference between evaporation and boiling?
Evaporation occurs only at the surface, while boiling occurs throughout the liquid.
What happens to the rate of evaporation as the temperature increases?
The rate of evaporation increases as temperature increases.
What is the boiling point of a liquid?
The temperature at which molecules throughout the liquid can change to the gaseous state.
Which of the following statements about the temperature of a boiling liquid is true?
The temperature of a boiling liquid remains constant until all molecules turn into a gas.
What is the primary factor that determines the rate of evaporation for a liquid?
The temperature of the liquid.
