  • The Pros And Cons Of Evaporation

    1736 Words  | 7 Pages

    As the sun heats up the Earth, the water in the ocean, surface waters, and waters held by plants evaporates and turn into water vapor - very small particles that mix with the air. This process is called evaporation. During evaporation, the ocean is the biggest contributor of water vapor since it is the largest body of water. In the case of plants, water absorbed by the roots and distributed to the different parts also evaporates through the leaves in the process called evapotranspiration. This is

    downside to this plan is that in order to create a canal and to flow water into it, it would expose much more of the basin along the shore. The most realistic plans to save the Salton Sea involve a multilevel approach including the use of dikes, evaporation systems, water treatment and desalination facilities, and artificial rivers to transport water. However, in order to restore the Salton Sea, salt is not the only thing that must be removed. Nutrient removal must be performed at the tributaries to

  • The Mpemba Effect: Hot Water Freezes Faster Than Cold Water

    1149 Words  | 5 Pages

    The Mpemba effect is that, under certain circumstances and experimental parameters, it is observed that hot water freezes faster than cold water which sounds implausible since hot water, with a higher temperature than cold water, has a higher amount of internal energy which has to be lost before it starts to change its state and turn into ice. The effect got its name from Erasto Mpemba who discovered the effect that hot water freezes faster than cold water after he discovered that hot ice-cream freezes

    survive without it. It keeps things cool. It makes breathtaking waterfalls. But, what does it do apart from being drunk, be splashed and swum in, be washed with? Answer. The water cycle. A lot more things happen to water than you think. Evaporation The Evaporation stage is when the water evaporates. The heat from the sun makes the water so hot that it turns into a gas called water vapour, and rises up into the air. This is the first step in the water cycle. Condensation Condensation is
