Solid
திட நிலை
In a solid, particles are tightly packed together in a regular arrangement. Solids have a definite shape and volume that does not change unless a force is applied.

Particle Arrangementதுகள் அமைப்பு
Particles are very close together in a fixed, ordered arrangement. They vibrate in place but cannot move past each other.
துகள்கள் நிலையான, ஒழுங்கான அமைப்பில் மிக அருகில் உள்ளன. அவை தங்கள் இடத்தில் அதிரும், ஆனால் ஒன்றையொன்று கடந்து செல்ல முடியாது.

State Changes From Solidநிலை மாற்றங்கள்
When a solid is heated, its particles gain enough energy to break free from their fixed positions and flow — it melts into a liquid.
Example: Ice melts into water at 0°C (273 K).
Some solids change directly into gas without passing through the liquid state when heated.
Example: Dry ice (solid CO₂) sublimes into carbon dioxide gas at room temperature.

Did You Know?உங்களுக்கு தெரியுமா?
★ Diamond — the hardest natural solid — is made of carbon atoms arranged in an extremely strong tetrahedral lattice. Its melting point is about 3,550°C, the highest of any element.
State changes at a glance
Matter changes state when energy is added or removed. Heating adds energy, causing particles to move faster until they change state. Cooling removes energy, slowing particles until they change to a lower energy state.
