One-liner

A solid can have a fixed shape because its particles are tightly packed in a rigid arrangement.

One-liner

The fourth state of matter is Plasma.

One-liner

Gamma radiation is the most energetic among alpha, beta, and gamma radiations because it consists of high-frequency electromagnetic waves with no mass.

One-liner

Solid has the minimum spaces among particles because its particles are tightly packed in a fixed arrangement.

One-liner

The path traced by beta particles in air is erratic due to their low mass and repeated collisions with air molecules.

One-liner

The average distance an alpha particle travels in air before losing its ionizing ability is called its Range.

One-liner

Plasma is the lightest form of matter, being an ionized gas with extremely low density.

One-liner

The impeller is the rotating component in a compressor that directly compresses air by accelerating it outward through centrifugal force.

One-liner

Pseudo solid is Glass, which is an amorphous solid that flows very slowly over time like a supercooled liquid.

One-liner

The tunnel effect makes alpha decay possible by allowing alpha particles to escape the nucleus despite insufficient energy to overcome the nuclear barrier classically.
