Question 2

Which statement below best explains why the density of water decreases as it is cooled from 4.0 $\degree$C to its normal freezing point?

Question 7

Which statement below regarding capillary action is FALSE?

Accepted Answer

Capillary action occurs due to the adhesive force between the liquid and the walls of the tube and the cohesive force within the liquid molecules themselves, allowing the liquid to move up the tube without the need for an external force.

Question 8

Question 9

Which liquid below will have the highest surface tension?

Accepted Answer

Water has the highest surface tension among the given options due to its ability to form hydrogen bonds, which are stronger intermolecular forces compared to the forces present in the other liquids listed.

Question 10

The temperature at point a in the phase diagram below is the

Accepted Answer

The answer of The temperature at point a in the...

Question 11

Water forms a concave meniscus in a glass tube because

Accepted Answer

The concave meniscus is formed because the adhesive forces between water molecules and the glass wall are stronger than the cohesive forces between water molecules. This causes the water to cling to the sides of the glass tube more strongly than it clings to itself, resulting in a concave shape.

Question 20

The resistance of a liquid to an increase in its surface area is

Accepted Answer

Surface tension is the property of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.
