Interview eye witnesses to collect the actual experiences of people affected by a cyclone.

When we concept that one mole of a substance contains the same numbers of elementary entities or one mole of any other substance, we don’t actually need to know what that number is. Sometimes however we will need to work with the actual number of elementary entities in a mole of substance. This number is called Avogadro.s number. N_(A)=6.022137xx10^(23) molecules The unit mol^(-1) which we read as per mole signifies that a collection of N_(A) molecular level entities is equivalent to one mole at the macroscopic level. For example a mole of carbon contains 6.02xx10^(23) atoms of C. A mole of oxygen gas contains 6.02xx10^(23) molecules of O_(2) . The number of atoms present in 8 g of ozone is

Read the following information and answer the given questions. To understand the functional relationship between these phases of cell cycle Dr.N.Rao and his research associate Dr.Johnson conducted experiments on cell fusion technique.His researches revealed that the cell cycle is sequential ,unidirectional had controlled by a series of chemical signals.His experiments are considered to be a milestone in the cell cycle studies.This study threw a new hope of ray for the budding scientists to carry out reseraches on cell division. G_+1:3.5 hrs,M:1 hr are the stages in a cell cycle which occur in a manner with specific time. G_1,S,G_2 stages are collectively called……………?

In an experiment on the specific heat of a metal, a 0.20 kg block of the metal at 150^(@) C is dropped in a copper calorimeter (of water equivalent 0.025 kg containing 150 cm^(3) of water at 27^(@)C . The final temperature is 40^(@) C . Compute the specific heat of the metal. If heat losses to the surroundings are not negligible. Is your answer greater or smaller than the actual value for specife heat of the metal ?
