Solution
The correct option is A True
Sulphur is an element, air is a mixture and steam is a compound.
An element is composed of only one kind of atoms, and sulphur is made up of only sulphur atoms. Hence, sulphur is an element.
A compound is defined as a pure chemical substance consisting of two or more different chemical elements. Water is a compound formed by chemical combination of hydrogen and oxygen elements. When it is heated, it evaporates, and the water vapours formed are known as steam. Hence, steam (gaseous form of water) is a compound.
Air is a mixture of various gases, such as nitrogen, oxygen, carbon dioxide, etc.
