1.	When we raise the temperature of a body, the molecules and atoms move with greater kinetic enery. Assume that "the temperature" is the manifestation of only the kinetic energy is atomic and subatomic levels and no mass change (excess//defect) occurs due to heating. Now a solid material is supplied with heat at a constant rate. The temperature of the material is changing with the heat input as shown in the graph. `BC` and `DE` are parallel to the Heat-input axis In `BC` and `DE` A. kinetic energy increasesB. potential energy increasesC. kinetic energy decreasesD. potential energy remains constant
Answer» In `BC` and `DE` temperature remains constant `rArr K.E.` remains constant `rArr` Heat goes to increasing the `P.E.`

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.
