12 Questions
When a substance is cooled, the atoms/molecules gain energy and move faster.
False
The volume of a substance decreases when the particles spread further apart.
False
Temperature is a measurement of the average speed of atoms/molecules.
True
The faster the atoms/molecules move, the lower the temperature.
False
When atoms/molecules get closer together, the volume of the substance increases.
False
As a substance is warmed, the collisions among atoms/molecules become weaker and less frequent.
False
When a substance is cooled, the atoms/molecules lose energy and move slower.
True
Temperature is a measurement of the average speed of atoms/molecules.
True
Heating a substance results in the atoms/molecules spreading further apart.
True
Cooling a substance causes the atoms/molecules to compress and get closer together.
True
The faster the atoms/molecules move, the higher the temperature.
True
When particles are moving slower, that results in a lower temperature.
True
Test your knowledge on the concepts of heating and cooling of substances, energy transfer, changes in speed of atoms/molecules, and temperature measurement. Understand how energy transfer affects the movement of particles and results in temperature changes.
