Assertion: Water drop stick to glass surface. Reason: Water have properties of surface tension.
1 If both assertion and reason are true and reason is the correct explanation of assertion.
2 If both assertion and reason are true but reason is not the correct explanation of assertion.
3 If assertion is true but reason is false.
4 If both assertion and reason are false.
Explanation:
B Water drop stick to glass surface and water have properties of surface tension. Adhesive force between glass and water molecules is greater than cohesive force between water molecule, so both assertion and reason are true but reason is not the correct explanation of assertion.

Assertion: Sometimes insects can walk on water. Reason: The gravitational force on insect is balanced by force due to surface tension.
1 If both assertion and reason are true and reason is the correct explanation of assertion.
2 If both assertion and reason are true but reason is not the correct explanation of assertion.
3 If assertion is true but reason is false.
4 If both assertion and reason are false.
Explanation:
A Sometimes insects can walk on water because the gravitational force on insect is balanced by force due to surface torsion.

Assertion: Water drops take spherical shape when falling freely. Reason: Water has minimum surface tension among all liquids.
1 If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
2 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
3 If Assertion is correct Reason is incorrect.
4 If both the Assertion and Reason are incorrect.
Explanation:
D Water drops take oval shape when falling freely and surface tension of water is not minimum among all liquids. So both assertion and reason are incorrect.

Assertion: Water at the foot of the water fall is always at different temperature from that at the top. Reason: The potential energy of water at the top is converted into heat energy during falling.
1 If both assertion and reason are true and reason is the correct explanation of assertion.
2 If both assertion and reason are true but reason is not the correct explanation of assertion.
3 If assertion is true but reason is false.
4 If both assertion and reason are false.
Explanation:
A Water at the foot of a water fall is always at a different temperature from that at the top because the potential energy (mgh) of water at the top is converted into kinetic energy which further is converted into heat energy during the fall. So temperature of water increases.
