(i)Stanley Miller designed a glass apparatus comprising a gas flask, a condenser , and a liquid flask interconnected with tubes and fitted with source of energy . This apparatus simulated the conditions on the primitive earth , including a reducing atmosphere and an ocean .
(ii)He provided energy , for the interaction of gases present as mixture in the apparatus, in the form of electric sparks of 75,000 volts from electrodes in the gas flask.
(iii)Miller circulated , in this apparatus , a mixture of methane, ammonia and hydrogen gases in the ratio of 2:2:1 and water vapour at `800^@C` . After electric spark, the gases were condensed in a narrow tube and passed through a liquid flask. Here, energy was provided as heat with an electric heater . This resulted in mixture of small organic molecules in the gas flask (atmosphere ) and were carried by condensation (rain ) to the liquid flask (ocean)
