Answer: On increasing temperature at which adsorption is carried out decreases the extent of physisorption.
Explanation:
An adsorption where molecules of the adsorbate are placed or held on the surface of adsorbent by Vander waals forces is called physisorption.
There is basically physical bonding between the molecules of gas to the surface of a solid or liquid.
Physisorption is reversible in nature and occurs at low temperatures.
It is not specific in nature which means that all gases are adsorbed on the surface of every solid substance to some extent.
Thus, we can conclude that on increasing temperature at which adsorption is carried out decreases the extent of physisorption.

Answer:
moles of water in 
of water.
Explanation:
Mass of water = 
Molar mass of water = M = 18 g/mol
Moles = n = 
So, there are moles of water in of water.
