animation on states of matter

Any system where there is a constant exchange of matter and energy from the surrounding environment is called as open system. All living organisms represent open systems. Any state of a system where the rate of input of energy and matter is equal to the rate of..

Jan Baptista van Helmont discovered the presence of carbon dioxide in the year 1630. Although the percentage of carbon dioxide in air is very small, it plays a vital role in nature. All the food that is produced on the earth is by photosynthesis, which employs carbon dioxide as the basic raw materi..

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 'macroscop..

Phosphorus is widely distributed in nature. It does not occur in free state since it can be very easily oxidised. It is usually present in rocks in the combined state as phosphates. The main phosphate rocks are: Phosphorite: Ca 3 (PO 4 ) 2 Fluorapatite: 3Ca 3 (PO 4 ) 2 . CaF 2 C..

Ammonia is produced by decay of plant and animal tissues. Nitrogenous organic matters like urea in the urine and excreta of animals get acted upon by bacteria releasing ammoni..

Summary - Both living organisms and non-living matter are composed of some basic elements and are bound by the same physical laws. However, living organisms differ from non-living matter in some specific aspects. Living organisms exhibit a kind of organisation from molecular lev..

Primary source of energy is dead organic matter called 'detritus' which are fallen leaves, plant parts or dead animal bodie..

Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating free nitroge..

Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atoms of a solid can have only vibrational motion, because they are held in their positions by strong intermolecular force..

The physical meaning of entropy is that entropy is a measure of degree of disorder (or randomness) of a system. The relation between entropy and disorder provides a suitable explanation for entropy change in various processes. The greater the disorder in a system, the higher is the entropy. Obviou..
