What is " Clasius Claperon" equation ?

The dependence of vapour pressure and temperature is given by CLASIUS CLAPERON equation.

Vapour pressure of a particular liquid system is only the function of temperature only. It is independent from all other 

What is "Anoxia" conditions ?

At high altitudes the partial pressure of oxygen is less than that at the ground level. This leads to low concentrations of oxygen in the blood and tissues of people living at high altitudes or climbers. Low blood oxygen causes climbers to become weak and unable to think clearly, symptoms of a condition known as anoxia.

What is bends condition and what is relation of bends with Scuba divers ?

Scuba divers must cope with high concentrations of dissolved gases while breathing air at high pressure underwater. Increased pressure increases the solubility of atmospheric gases in blood. When the divers come towards surface, the pressure gradually decreases. This releases the dissolved gases and leads to the formation of bubbles of nitrogen in the blood. This blocks capillaries and creates a medical condition known as bends, which are painful and dangerous to life.

 To avoid bends, as well as, the toxic effects of high concentrations of nitrogen in the blood, the tanks used by scuba divers are filled with air diluted with helium (11.7% helium, 56.2% nitrogen and 32.1% oxygen).

What is effect of temperature on vapour pressure ? Explain with CLASIUS CLAPERON equation.

Factors affecting vapour pressure:

(A) Temperature:.

(1) The temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure is called its boiling point.

(2) Vapour pressure is directly proportional to theTemperature so that on increasing temperature the rate of evaporation increases and rate of condensation decreases and hence vapour pressure increases.

(3) The dependence of vapour pressure and temperature is given by CLASIUS CLAPERON equation.

(4) Vapour pressure of a particular liquid system is only the function of temperature only. It is independent from all other 

What is vapour pressure and What is effect of temperature on vapour pressure ?

VAPOUR PRESSURE:

(1) If a sample of water in its liquid phase is placed in an empty container, some of it will vaporize to form gaseous of water. This change is called evaporation.

(2) The pressure exerted by the vapour (molecules in the vapour phase) over the surface of the liquid at the equilibrium at given temperature is called the vapour pressure of the liquid.

OR

(3) It is the pressure exerted by the vapour when vapours are equilibrium with the liquid.

(4) The pressure exerted by vapours is called unsaturated vapour pressure or partial vapour at non equilibrium condition.

(1) The temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure is called its boiling point.

(4) Vapour pressure of a particular liquid system is only the function of temperature only. It is independent from all other factors like surface area, amount of liquid, available space etc.
