Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). nuclear fission), provided that the transferred heat is sufficient for the evaporation of the considered amount of water. Just how much power will the world consume? Will it be better to possess a black metal container or perhaps a black plastic? The result is that the waters of the Dead Sea have the highest salinity and density of any sea in the world, too high to support life. In conclusion: it is definitely a bitfaster to boil water in a coveredpot. &=0.408 Note: This section of the Water Science School discusses the Earth's "natural" water cycle Condensation is the process of gaseous water (water vapor) turning into liquid water. Is the implication here that the wick soaks up the water and then that water evaporates, and repeat? Evaporation can be compared to that of a sponge. Pure or distilled water evaporates faster than saltwater and other types of impure water. Evaporation happens when a liquid substance becomes a gas.When water is heated, it e vaporates.The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation rates are generally higher in hot, dry and windy climates. Very little water vapor escapes the pot or pan while covered. If using hot air toevaporate water, increased velocity will increase the speedof evaporation. Perhaps you've never seen snow. On a much smaller scale, you can carry out a simple experiment at home to establish how long it takes for water to evaporate, and what factors speed up the process.
