quantitative analysis - estimation of elements after qualitative analysis of elements the another step in the determination of molecular formula of
method for detection of elements - oxygenthere is no any type of satisfactory qualitative method for the detection of oxygen though its presence can
although conduction does occur in liquids and gases also heat is transmitting in these media mostly by convection in that phenomenon the real motion
method for detection of elements - phosphorusphosphorus is detected through fusing the organic compound along with sodium peroxide while phosphorus
beilstein test or copper wire test - halogensa clean copper wire is heated in the bunsen flame till it does not impart any type of green colour
heat may be transmitted from one body to the other by any of three possible ways conduction radiation and convection in the conduction convection
oxidation test - sulphur sulphur can as well be tested by oxidation test the organic compound is fused along with fusion mixture a mixture of sodium
whenever there is a relative speed among a source of sound and the listener the apparent frequency of sound listen by the listener is dissimilar from
the impression of sound heard by our ears persist in our mind for 110th of a second if another sound is heard before 110 second is over the
beat period the time interval among two successive beats is called as beat periodbeat frequency the number of beats given per second is called as
if the intensity of sound is maximum at time t 0 one beat is known as formed when intensity changes into maximum again after becoming minimum once
