Question

The surface tension of isopropyl alcohol in air has a value of 22.39 units and
the surface tension of water in air is 72.86 units. Which two statements are
true?
A. Isopropyl alcohol will have a higher boiling point than water
because the forces between the molecules are greater.
B. Isopropyl alcohol will have a lower boiling point than water
because the forces between the molecules are smaller.
c. Isopropyl alcohol will have a more curved meniscus than water
because the forces between the molecules are greater.
D. Isopropyl alcohol will have a flatter meniscus than water because
the forces between the molecules are smaller.

Answer 1

Answer:

B. Isopropyl alcohol will have a lower boiling point than water

because the forces between the molecules are smaller.

D. Isopropyl alcohol will have a flatter meniscus than water because

the forces between the molecules are smaller.

Explanation:

Answer 2

Isopropyl alcohol will have a lower boiling point than water because the forces between the molecules are smaller. Isopropyl alcohol will have a flatter meniscus than water because the forces between the molecules are smaller. Hence, options B and D are correct.

What is surface tension?

Surface tension is the force that acts parallel along the surface of a liquid which in turn makes the surface of the liquid behaves like an elastic material.

Surface tension, as the name implies, acts on the surface of a liquid giving it some elastic properties; it is a product of the inherent properties of the molecules of the liquid.

For example, water possesses surface tension which is why when a pin or a needle is gently placed on the surface of the water it floats. Surface tension also accounts for the fact that some insects can walk on water.

Hence, options B and D are correct.
