Which is the correct order of states of matter by increasing kinetic energy of particles?
AGas, liquid, solid
BLiquid, solid, gas
CSolid, liquid, gas
DSolid, gas, liquid
Answer & Solution
Correct answer: C. Solid, liquid, gas
1. Particle energy is highest where motion is greatest.
2. Solids vibrate weakly; their particles have the least kinetic energy.
3. Liquid particles slide around with more energy than solids.
4. Gas particles fly freely with the most energy.
5. So the order is solid < liquid < gas.
