The specific heat of water and steam (water vapor) are 4.18 J/g C and 2.10 J/g C respectively. Heating a 74.0 g sample of water from 88.3 C to water vapor at 112.5 C requires 172.58 kJ of heat. Calculate the heat of vaporization of water in kJ/g. Assume the boiling point of water is 100 C

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.
