Explanation

Germanium is a semiconductor.

It commonly used in electronics for its ability to conduct electricity under certain conditions.

It has properties between those of a conductor and an insulator, similar to silicon.

Explanation

The value of absolute zero is -273°C.

It is the theoretical temperature where all molecular motion stops.

It is equivalent to 0 Kelvin in the Kelvin temperature scale.

Explanation

Coulomb's law deals with the force between electric charges, not the relationship between volume and pressure of a gas.

The inverse relationship between volume and pressure is explained by Boyle's Law, not Coulomb’s law.

Explanation

The density of water is maximum at 4°C, not 5°C.

At 4°C, water reaches its highest density before expanding when cooled further into ice.

Explanation

Water freezes and melts at 0°C (32°F) under standard atmospheric pressure.

At this temperature, water can exist in both solid (ice) and liquid forms depending on whether heat is being added or removed.
