Question

A closed bottle containing water at 30°C is
carried to the moon in a space-ship. If it is placed
on the surface of the moon, what will happen to
the water as soon as the lid is opened :
(a) उबलने लगेगा
Water will boil
(b) जम जायेगा
Water will freeze
(c) इसमें कोई परिवर्तन नहीं होगा
Nothing will happen on it
(d) H, और 0, में विच्छेदित हो जावेगा
It will decompose into H, and O,​

Answer 1

according to me, as there is negligible air pressure on the surface of moon, the water will boil due to low pressure and convert into its gaseous form which is steam.
