Question 2 of 10
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 iwo statements are
true?
A sopropyl alcohol will have a more curved meniscus than water
because the forces between the molecules are greater
B. Isopropyl alcohol will have a higher boiling point than water
because the forces between the molecules are greater
o Isopropyl alcohol will have a flatter meniscus than water because
the forces between the molecules are smaller
D. Isopropyl alcohol will have a lower boiling point than water
because the forces between the molecules are smaller
