10 Questions
What happens to the speed of atoms/molecules when energy is transferred to a substance?
Speed increases
How does temperature change relate to the speed of atoms/molecules?
Directly proportional
What happens to the volume of a substance when its atoms/molecules move faster?
Volume increases
What occurs when a substance is cooled?
Atoms/molecules move slower
How does cooling a substance affect the collisions between atoms/molecules?
Collisions are weaker and less frequent
When a substance is heated, the atoms/molecules move slower.
False
Cooling a substance leads to a decrease in the volume of the substance.
True
The speed of atoms/molecules directly affects the temperature of a substance.
True
Heating a substance always results in stronger and more frequent collisions between atoms/molecules.
True
When a substance is cooled, the atoms/molecules themselves shrink.
False
Learn about the basic concepts of heat transfer and temperature, including how energy is gained or lost when heating or cooling a substance, and how it affects the speed of atoms and molecules. Understand how temperature is related to the average speed of particles.
