State and explain Lichateliers principle and discuss its application.

1. Le-Chatelier's principle

Equilibrium state of a reversible reaction can be disturbed by changing temperature, pressure, volume and concentration of reaction system. This fact was thoroughly studied by a French Chemist Henry Louis Le-Chatelier in 1884. He made a generalization which is termed as Le-Chatelier's principle. This principle states that, ‘when a system in equilibrium is subjected to a change in temperature, pressure, volume and concentration, the equilibrium shifts in such a...

Describe structure of respiratory system of human being with well diagram ?

Respiration is necessary for every living being, and there’s a distinct, special organ system working constantly to carry it out. In humans, it is called the respiratory system.

The human body is a complex structure of many organs and organ systems, and the human respiratory system is one of them. The respiratory system functions continuously without a break, as we breathe by inhaling oxygen and exhaling carbon dioxide. Breathing is essential for our survival and effective for the functioning...

Write the differences between the following.i. Force and pressureii. Archimede's principle and the law of flotationiii. Upthrust and pressureiv. Density and relative density

i. Force and pressure

Force	Pressure
It is the product of mass and acceleration.	It is the total force applied per unit area.
Force = m.a	Pressure = F/A
Its SI unit is Newton (N).	Its SI unit is Pascal (Pa).

ii. Archimede's principle and the law of flotation.

Archimede's principle	Law of flotation
It states that when a body is partially or totally immersed in a liquid, it experiences the upthrust equal to the weight of the liquid displaced by it.	It states that a body floats on a liquid if it can displace...
