In the experiment of Stanely Miller the temp. of water vapour was :

Options

A. `1200^(@)C`
B. `1000^(@)C`
C. `800^(@)C`
D. `1500^(@)C`

Answer

**Step-by-Step Solution:**

1. **Understanding the Experiment**: The Stanley Miller experiment aimed to simulate the conditions of early Earth to explore how organic compounds could form from inorganic materials.

2. **Components of the Experiment**: Miller used a mixture of gases that were thought to be present in the early atmosphere, including hydrogen, methane, ammonia, and water vapor.

3. **Temperature Setting**: In the experiment, the temperature of the water vapor was set at 800 degrees Celsius. This high temperature was crucial for simulating the conditions that might have existed during thunderstorms on early Earth.

4. **Electric Spark**: An electric spark was introduced to mimic lightning, which is believed to have played a role in the formation of organic molecules.

5. **Results**: The experiment resulted in the formation of amino acids, which are the building blocks of proteins, supporting the idea of chemical evolution.

6. **Conclusion**: Therefore, the temperature of water vapor in Stanley Miller's experiment was indeed 800 degrees Celsius.

**Final Answer**: The temperature of water vapor in the experiment of Stanley Miller was 800 degrees Celsius.
