Question

‘Matter is made up of particles. Explain with an example.

Answer 1

Hint: Matter is anything that has mass and occupies a space (it has volume). On earth, it is in the form of solid, liquid, or gas. Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. In a liquid, the particles are attracted to each other but not as much as they are in a solid.

Complete answer:
Matter is made up of small particles that are too small to be seen, even with a powerful microscope. Molecules can move from one physical state to another and not change their atomic structure. Example, Oxygen gas has the same chemical properties as liquid oxygen. The liquid state is colder and less energy, but the molecules are the same.
Another example is Water (\[{H_2}O\]). A glass of water has many water molecules which are very minute. A water molecule is made up of two Hydrogen (\[H\]) atoms and one oxygen (\[O\]) atom. Water molecules can be divided into even smaller units. It has the same molecular structure whether it is a solid, gas, or liquid. The pieces of matter that result from dividing a water particle are no longer water. They are examples of the most basic units of matter called atoms.

Additional information:
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

Note:
Note that mass is the amount of matter in an object. Mass is a measure of the matter in an object while weight is a measure of gravity’s pull on an object. Volume is the amount of space something occupies. Different states of matter will fill volumes in different ways.
