Question

What will happen if the pressure is reduced to 0.01.mm of mercury

Answer 1

In general, the surface temperatures decreases with increasing distance from the sun. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface to above the melting point of lead, about 880 degrees Fahrenheit (471 degrees Celsius).

Answer 2

The gas present in the discharge doesn't lead to the atmospheric pressure.

When the pressure is diminished beneath the atmospheric pressure, the gas present inside the cylinder begins leading and various wonders are seen as we decline the pressure steadily.

      As the weight in the cylinder is decreased to 10 mm of Hg a release is found to begin between the two terminals, joined by a breaking sound.

The release travels in a crisscross way and the shading is pale blue.

These sporadic pale blue lines are called blue streamers.
