What happens to the motion of the particles as temperature rises?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. The particles move faster.
As temperature rises, the particles move faster. This is because heat provides energy to the particles, increasing their kinetic energy. As a result, the particles begin to vibrate more rapidly in solids, move more freely in liquids, and become highly energetic and fast-moving in gases. This increase in motion due to rising temperature can also lead to changes in the physical state of a substance, such as melting or boiling, depending on the amount of heat energy absorbed.
