Explanation carbon cycle

Posted by Mansha Balchandani 7 years, 6 months ago

CBSE > Class 09 > Science

1 answers

Yogita Ingle 7 years, 6 months ago

Carbon enters life forms through the process of photosynthesis. Photosynthesis is the process by which plants prepare food in the presence of sunlight and chlorophyll. During photosynthesis, carbon dioxide and water combine to produce glucose and oxygen. This changes the atmospheric carbon into glucose molecules.
Glucose, which is a source of food, is utilized by organisms to produce energy during respiration. During this process, glucose is broken down in the presence of oxygen to produce carbon dioxide.
Thus, through the processes of photosynthesis and respiration, carbon is utilized and then returned to the environment.
All organisms do not need oxygen to break down glucose and produce energy. The organisms which survive in the absence of oxygen are called anaerobes.
Another process that releases carbon dioxide is called combustion. It is the process of burning. Many substances release carbon dioxide on burning. Vehicular emissions, industrial fumes, and the gases released during the process of cooking are some instances during which carbon dioxide is released.

Ushaan Kapoor 7 years, 6 months ago

Dear student, Addition of carbon disulphide to a mixture containing iron fillings and sulphur powder, leads to formation of a clear yellow solution when sulphur powder dissolves in carbon disulphide, on gentle shaking. Iron fillings being insoluble settle in the bottom. These can be separated by filtration.

Define charge

Posted by Pawan Punj Bais Bais 7 years, 6 months ago

Yogita Ingle 7 years, 6 months ago

Electric Charge is defined as the amount of energy or electrons passing from one body to another either by conduction, induction or other specific methods. There are two types of electric charges namely positive charge and negative charges

The charge is denoted by the symbol ‘q’ and its standard unit is Coulomb. Mathematically charge is the number of electrons multiplied by the charge on 1 electron. That is

Q = ne

where q is a charge, n is a number of electrons and e is a charge on 1 electron (1.6 × 10^-19C )
