Chapter 15, Problem 10STP

Solution

To determine:

The source of energy that could have been present on early earth other than lightening.

Introduction:

Scientists Stanley miller and Harold Urey were the first to show that simple organic molecules could be made from inorganic compounds. Many experiments were conducted under conditions that were similar to atmosphere of early Earth. They built a glass apparatus as shown in the given figure.

If there were no lightning, energy from colliding meteorites, solar energy and Earth’s heat might also have caused these reactions.
