Question

Sulphur is an element, air is a compound and steam is a mixture.

• A. True
• B. False

Answer 1

The correct option is B

False

When water is heated, it evaporates, and the resulting water vapours are also known as steam. So steam is essentially water in the gaseous state, with exactly the same composition. Steam is made of oxygen and hydrogen atoms, so it is a compound. A compound is a chemical combination of two or more elements.
Air is a homogeneous mixture of gases. Sulphur is an example of an element.
