1.	Osmotic pressure of naphthalene solution at `27^@C` is 500 mm Hg. When the solution is diluted and temperature is raised to `47^@C`, osmotic pressure of the solution becomes 105 mm Hg. The extent of dilution approximately is :-A. 3 timesB. 5 timesC. 7 timesD. 4 times
Answer» Correct Answer - B `pi_1/pi_2 =(C_1T_1)/(C_2T_2)` `500/105 = (n_1 /V_1 xx300)/(n_1/V_2 xx 320)` `500/105 =V_2/V_1 xx 300/320` `500/105xx320/300 =V_2/V_1` `5 = 320/63=V_2/V_1`

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example. These bacteria convert atmospheric nitrogen into nitrogenous compound and fix in the soil.The organisms which enrich the nutrient quality of the soil are called(a) Microbes(b) Biofertilizers(c) Yeast(d) Biopesticides
