Question

The formation of tiny bubbles when a beakerof water is mildly heated indicates that

a. air is less soluble in water at higher tem-peratures.correct
b. the lattice energy of water is large.
c. water is being decomposed into hydrogenand oxygen.
d. the liquid is at its boiling point.
e. water is being extensively hydrogen bonded.

Answer 1

a. air is less soluble in water at higher temperatures

Step-by-step explanation:

At higher temperatures , the gases molecule present in water begin to vibrate. This increase in energy of the molecules cause them to break their inter molecular bond and escape out. When these gases molecule escape out we can see bubble formation in the water. So, on increasing the temperature air solubility in water decreases.
