One-liner

α-radiation is highly ionizing than γ-radiation because alpha particles are heavy, slow-moving, and carry a +2 charge, causing intense ionization along their short path.

One-liner

Pair production is the phenomenon in which a gamma-ray photon transforms into an electron and a positron in the presence of a nucleus.

One-liner

Blotting paper absorbs water due to capillary action, where liquid rises through narrow spaces against gravity.

One-liner

Liquids have a definite volume but no definite shape — they take the shape of the container they are in while maintaining a constant volume.

One-liner

There are 3 classical states of matter: solid, liquid, and gas.

One-liner

Newtonian mechanics can describe it does not apply in nanotechnology because at the nanoscale, quantum mechanics governs behavior instead of classical Newtonian physics.

One-liner

A shaving blade floats on water due to surface tension, which creates an elastic-like film on the water surface that supports light objects.

One-liner

The spreading of fragrance or scent in air is due to diffusion.

One-liner

Water is not a solid; it is a liquid at room temperature, while ice, iron, and wood are all solids.

One-liner

The mobility of liquids is lesser than gases because gas particles have the highest kinetic energy and move most freely among the three states of matter.
