In Miller's experiment, he used a mixture of CH₄, NH₃, H₂ and water vapour in a closed flask to mimic early earth conditions. What was the temperature at which this flask was kept?

800 $°$ C

1200 $°$

200 $°$ C

400 $°$ C

Solution

800 $°$ C

Initially, Oparin and Haldane proposed that first form of life could have come from pre- existing non- living organic molecules. The conditions were high temperature, volcanic eruption , storms, reducing atmosphere consisting of CH₄, NH₃ etc. Later in 1953, Miller created similar conditions in a laboratory and created an electric discharge in a closed flask containing CH₄, H₂ and NH₃ and water vapour at 800 $°$ C.
