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

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
