An external pressure P is applied on a cube at 0^@C so that it is equally compressed from all sides. K is the bulk modulus of the material of the cube and alpha is its coefficient of linear expansion. Suppose we want to bring the cube to its original size by heating. The temperature should be raised by:

Paragraph based question Read the following paragraphs and answer the questions based on it. After the death of apex consumers, their energy becomes available to the decomposers. Fungi and other micro-organisms decompose the bodies of dead animals. They are called decomposers. In the process of obtaining food from the remains of organisms, decomposers convert them into simple carbon compounds. These substances easily mix with air, water and soil from where they are again absorbed by plants and incorporated into the food chain. Name the decomposers. Where are they found?

complete the paragraph by choosing the appropriate words given in the brackets : (gamete, crossing over, haploid, Meiosts-II,meiosis-I, diploid) .............. is just like mitosis. In this stage, the two haploid daughter cells formed in ......... undergo division by separation of recombined sister chromatids and four .................... daughter cells are formed. Process of ........ production and spore formation occurs by meiosis. In this type of cell division, four haploid (n) daughter cells are formed from one ..........cell. During this cell division, ....................occurs between the homologous chromosomes.
