Read the following paragraph and answer the questions given below it: The resistance of a metal falls when cooled below room temperature. Many scientists believed that the value of the resistance would become constant at some very low temperature, allowing the current to flow with little or no resistance. H. K. Onnes successfully liquefied helium in 1908 by cooling it to about 4 K. In 1911, while investigating the electrical property of very pure mercury. Onnes discovered that at a temperature of 4.2 kelvin, its resistance practically vanished. This new state, on account of its extraordinary property, is now called the superconducting state and the phenomenon is called superconductivity. A superconductor, below a certain critical temperature, offers almost zero resistance to a flow of current through it. Onnes also discovered that a superconductor exhibits persistent current: once set up, the current continues to flow for a very long time without an electric potential difference driving it and without significant loss. Superconductivity is used in many diverse areas, such as magnetically levitated trains, transmission of electricity, increasing speed of computers, in MRI (magnetic resonance imaging). Name the scientist who discovered superconductivity.

Dihydrogen gas used in Haber's process is produced by reacting methane form natural gas with high temperature steam..The first stange reaction involves the formation of CO and H_2 .In second stage , CO formed in first stage,CO formed in first stage is reacted with more steam ion water gas shift reaction, CO(g)+ h_2o(g) hArr CO_2(g) +H_2(g) If a reaction vessel at 400^@C is charged with a n equimolar mixture of CO and steam such that P_(co) =P_(H_2O) = 4.0 bar what will be the partial pressure of H_2 at equilibrium? k_p =0.1

Use your brain power When the above compounds are mixed with water they combine with water. Complete the following table by writing the ions formed by their combination with water. NH_(3(g))+H_2 O_(l) to NH_4(aq)^+ +OH_(aq)^- . Na_2 O_(s)+……to 2Na_(aq)^+ +…… . CaO_(s)+H_2 O_(l) to ........ +……

Paragraph based questions : Read the following paragraph and answer, the questions based on it. The presence or absence of organs is the first, criterion for classification of plants. The presence or absence of separate conducting tissues for conduction of water and food is the next consideration for classification. Do the plants bear seeds? If they do then, whether the seeds are enclosed in a fruit or not is also an important criterion for classification. Finally, plants are grouped depending upon the number of cotyledons in the seeds. In 1883, Eichler, a botanist, classified the Kingdom Plantae into two sub-kingdoms. As a result, two sub-kingdoms, cryptogams and phanerogams were considered for plant classification. Who classified the plants? In what groups did he classify the plant kingdom?
