Nitrogen (N) occurs free in nature as diatomic nitrogen gas (N2).

It makes up about 78% of Earth's atmosphere and is a major component of air.

The other elements mentioned—antimony (Sb), arsenic (As), and phosphorus (P)—are typically found in combined forms rather than in their free elemental states in nature.

They commonly occur in various compounds and minerals.

For example: Today's temperature is degree Celsius, here is not a discrete variable and hence is a continuous variable.

Explanation

• Neutralization is a chemical reaction where an acid and a base combine to form a neutral solution, neither acidic nor basic, with a pH of 7.
• This process is commonly seen in reactions between strong acids and strong bases, resulting in the formation of a salt and water.

Explanation

Geothermal energy is the heat produced deep in Earth's core.

it is a clean, renewable resource that can be harnessed for use as heat and electricity

Explanation

Deserts have little vegetation and moisture to retain the heat absorbed during the day.

This lack of heat retention causes temperatures to drop rapidly at night.
