Assertion : Liquids are less compressible than gases. Reason : Very small free space is available between molecules in gases.
1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 If both Assertion is true but Reason is false.
Explanation:
Due to more random in liquid than gases.

How does the surface tension of a liquid vary with increase in temperature?
1 Remains same
2 Decreases
3 Increases
4 No regular pattern is followed
Explanation:
The magnitude of surface tension of a liquid depends on the attractive forces between the molecules. When the attractive forces are large, the surface tension is large. Increase in temperature increases the kinetic energy of the molecules and effectiveness of intermolecular attraction decreases, so surface tension decreases as the temperature is raised.

Statement A : A spherical water droplet gets flatened on a flat surface. Statement B : It becomes flat due to gravity.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Due to surface tension, liquid tends to have a minimum surface area. For a given volume of a liquid, sphere has the minimum surface area. Therefore, the small spherical drops of liquids get slightly flatened by the effect of gravity.

Which among the following has lowest surface tension?
Since surface tension depends on the attractive forces between the molecules, and hydrogen bonding a special type of dipole-dipole interactions in (2), (3) and (4) which is stronger than London forces of attraction in hexane.
