Rahul Poddar 8 years, 2 months ago

Pv=nRT, from this equation n/v=P/RT, here n is the number of mole and n=given mass/molar mass"n=m/M putting it in m/Mv=P/RT here m/v=density (d), d/M=P/RT, d=MP/RT here M/RT is constant, d=(M/RT) P, d is directly proportional to pressure

Amar Kumar 8 years, 2 months ago

Oil drop experiment was performed originally by the American physicist Robert A. Millikan in 1909. It measures the size of charge on a single electron. Apparatus consist of an atomizer, which helps to spray tiny droplets. By means of a short focal distance telescope, the droplets can be viewed by telescope.
