chemistry properties of matter intensive properties

State variables and functions may posses either extensive or intensive properties. Extensive properties are those, whose values depend on the quantity of matter contained in any system or size of the system. Typical properties are mass, volume, are..

Radioactivity - The discovery of the electron towards the end of the nineteenth century was the starting point of new avenues of research in science, which were to give physicists an insight into the structure and nature of the atoms of matter. In 1896, Henri Becquerel discovered that whe..

Introduction - The classification of matter into three different states, namely solid, liquid and gaseous state is termed as the physical classification of matter. Most properties of solid, liquid and gases that can be observed with our sense organs are called as 'macr..

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 classifications of matter are based o..

1. A colourless, odourless and tasteless gas. 2. Non-poisonous. 3. Its vapour density is 1. (Vapour density of air = 14.4). Thus it is much lighter than air. Passing hydrogen through soap solution can easily prove this. The bubbles formed will rise into the air. 4. Solubility of H 2 is very lo..

Sulphur dioxide gas exhibits bleaching properties in presence of moisture. It dissolves in water liberating nascent hydrogen. Coloring matter is bleached by reaction with nascent hydrogen. Nascent hydrogen removes oxygen atoms from the coloring matter (reduces coloring..

Dual Nature of Matter and Radiation - Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observ..

Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that some of the experimental facts regarding..

. The difference in properties of charcoal, graphite, diamond went unexplained in spite of being made up of same kind of atom..
