1.	It is predicted by the meteorologists that global warming will result in the flooding of oceans due to the melting of ice caps on the earth.1. Name the thermodynamic process involved in the melting of ice.2. Determine the heat energy required to melt 5kg of ice completely at 0°C. Latent heat of fusion of water is 3336 × 103 J Kg-1.3. During the melting process, what change will occur to its internal energy?
Answer» 1. Isothermal process 2. ∆Q = mL = 5 × 33.36 × 10⁵ = 16.68 × 10⁶J 3. Internal energy increases

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.
