classification of matter substances gas

The molecules of a gas are far apart. The inter-molecular force of attraction is negligible and they have no fixed freedom of motion. Hence gases have neither fixed shape nor volume. They completely occupy the container and take the shape and the volume of the container. Molecular st..

Types of Solutions Solution is defined as a homogeneous mixture of two or more chemical substances. The state of matter of a solution may be solid, liquid or gas. For example: common salt in water (liquid solution), air (gaseous solution), alloys (solid solution), ..

Summary Matter - anything which has mass, occupies space and can be perceived by our senses. Law of conservation of matter - matter can neither be created nor destroyed. The states of matter are solid, liquid gas, plasma and super cooled ..

Question 1 - Question: A substance has a definite volume but no definite shape. State whether this substance is a solid, liquid or a gas. Answer: The substance is a liquid. It has a definite volume but no definite shape and takes the shape of the container in..

This theory explains the physical properties of matter in terms of motion of its molecules. According to this theory, every substance (solid, liquid or gas) consists of a large number of minute particles called molecules . A molecule may be defined as the smallest part..

Writing balanced equations Definition of a Mole Molar mass of a molecule from its chemical formula and a table of atomic masses Converting the mass of a molecular substance to moles Number of particles or volume of gas at standard temperature and pressure Masses of react..

2) In a non-uniform magnetic material, these substances move from stronger parts of the field to the weaker parts. For e.g.,. when diamagnetic liquid is put in a watch glass placed on the two pole pieces of an electromagnet and current is switched on the liquid accumulates on the sides. [..

All around us are substances that are made of matter. Matter has mass and occupies some space. Different kinds of substances are made up of different matter. Matter can be thus classified in many ways. Two basic classificationsh..
