When water fill in bottles in 30 degree celsius and open the bottles in moon then what will happen/?

Answer 1

Answer:
A
.
The water sample will boil with alacrity.
Explanation:
The boiling point of any liquid is the temperature at which the vapour pressure of the liquid is equal to the ambient pressure, and bubbles of vapour form directly in the liquid. Normally, we speak of the normal boiling point, where the ambient pressure is

In a hard vacuum, however, such as would occur on the moon, the boiling point of a liquid would be much less than the normal boiling point, in that the temperature does not have to be raised so much so that the vapour pressure is equal to (or exceeds that of) the external pressure. I suspect that if you opened a bottle of water on the moon, it would be like the scenario when you open a can of soft drink that you have shook up, i.e. a fountain.

Answer 2

as in this case
the temp. starts decreasing as we know that in moon their is low temp. so if we put waters on about 30 degree then in moon it got deduct..
