Matter changes state from solid to liquid and from liquid to gases, when it?

مادہ ٹھوس سے مائع اور مائع سے گیسوں میں حالت بدلتا ہے، کب؟

Loses energy

Gains energy

Remains same energy

Has constant temperature

Explanation

Matter changes state from:

Solid to liquid (melting) when it gains energy
Liquid to gas (vaporization) when it gains energy

This is because the particles need more energy to break free from their rigid structure in solids and move more freely in liquids, and even more energy to escape into the air as gases.
