The greater the difference between wet and dry-bulb temperatures, the lower (higher or lower) the relative humidity percentage is (look at the data table for help). This is because the evaporative cooling effect makes the wet bulb’s temperature (warmer or cooler) compared to the dry bulb. Therefore, when the air is (dry or humid), the evaporative cooling effect will be (stronger or weaker).

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.
