Water Cycle/Properties of Water

When water vapor condenses, how much heat energy will be released into the atmosphere?

• 2260 joules/gram

• 334 joules/gram

• 4.18 joules/gram

• 2.11 joules/gram

Base your answer to the following question on the diagram below and on your knowledge of Earth science. The diagram represents the water cycle. Letters A through C represent different processes in the water cycle.

In order for process A to occur, liquid water must...

• gain 334 Joules per gram

• gain 2260 Joules per gram

• lose 334 Joules per gram

• lose 2260 Joules per gram

Which change in the heat energy content of water occurs when water changes phase from a liquid to a solid?

• gain of 334 Joules of heat energy per gram

• release of 334 Joules of heat energy per gram

• gain of 2260 Joules of heat energy per gram

• release of 2260 Joules of heat energy per gram

As water vapor changes phase from gas to liquid, each gram of water vapor

• releases 2260 joules of heat energy

• releases 334 joules of heat energy

• gains 2260 joules of heat energy

• gains 334 joules of heat energy

How much heat energy is required to change five grams of solid ice to liquid water at 0°C?

• 334 joules

• 1670 joules

• 2260 joules

• 11,300 joules

Most water vapor enters Earth’s atmosphere by the processes of

• condensation and precipitation

• radiation and cementation

• conduction and convection

• evaporation and transpiration
