Question

in which state of matter do particles move the fastest? a gas b liquid c none of these d solid

Explanation:

In the states of matter, gas particles have the highest kinetic energy and move the fastest. Solids have particles with low kinetic energy (vibrate in place), liquids have particles with moderate kinetic energy (slide past each other), while gas particles move freely and rapidly. So the correct option is A.

Answer:

A. Gas
