12 Questions
What happens when a substance is heated?
The atoms/molecules gain energy and move faster, resulting in stronger and more frequent collisions.
What is the relationship between temperature and the speed of atoms/molecules?
Temperature is a measurement of the average speed of atoms/molecules.
What happens to the volume of a substance when it is cooled?
The atoms/molecules get closer together, and the volume of the substance decreases.
What is the key difference between heating and cooling a substance?
Heating a substance means energy is transferred to it, while cooling means energy is transferred from it.
How do the atoms/molecules themselves behave during heating and cooling?
The atoms/molecules do not change in size during heating or cooling.
What is the effect of stronger and more frequent collisions between atoms/molecules when a substance is heated?
The atoms/molecules spread further apart, and the volume of the substance increases.
What happens to the volume of a substance when its atoms/molecules move slower?
The volume decreases
Which statement is true about the relationship between temperature and atom/molecule speed?
Higher temperature means faster atom/molecule speed
What occurs to the collisions between atoms/molecules when a substance is cooled?
Collisions become weaker and less frequent
In relation to heating a substance, what effect does gaining energy have on the atoms/molecules?
Atoms/molecules expand and spread further apart
What is the consequence of atoms/molecules moving faster in relation to temperature?
Increase in collisions between atoms/molecules
When energy is transferred from a substance, what happens to the temperature?
Temperature decreases
