Evaporation is important to our earth's water cycle. The loss of water from plants as water vapour through the pores of their leaves is called transpiration. Ans: (a) Blowing of balloon (b) Rolling out roti from dough ball. (6) These drops of water fall down on the earth in the form of rain. The evaporation rate depends on the temperature and humidity of the air, which is why sweat accumulates more on humid days, as it does not evaporate fast enough. (2) Water from wet roads and puddles near our homes and rooftops (formed during rains) also dries up and disappears by forming water vapour by the process of evaporation when the rain stops. Answer: The process used to separate slightly larger particles from a mixture by hand is called handpicking. When snow lying on high mountains melts, it forms water.

Question 4 State one large scale use of process of evaporation? The changing of a liquid into vapours or gas is called evaporation. The use of process of evaporation for separating a mixture is based on the fact that liquid vaporise easily whereas solids do not vaporise easily. Evaporation of water takes place from oceans, rivers ,lakes, ponds and soil whereas transpiration occurs from the leaves of plants and trees. Evaporation is used to obtain a solid substance that has dissolved in water or any other liquid. For example: Stone pieces can be separated from wheat or rice by handpicking. This pure water is collected in a beaker kept below the frying pan. Distillation involves two processes evaporation followed by condensation. Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. (False, High humidity in the atmosphere results decrease in the rate of transpiration.) Sea water is trapped in shallow lakes and allowed to stand there. (4) Now as we go higher and higher from the surface of earth, the temperature decreases, it becomes cooler and cooler.

Medical Definition of evaporation. Another typical illustration of evaporation is the evaporation of acetone that is used for removing nail polish. This is because though water forms vapour easily on heating, salt does not form vapour (or gas) at all. During winter in very cold regions, the water drops in the sky freeze to form snow (ice). When sea water is evaporated we get a mixture of salt. We can recover common salt from salt water mixture by the process of evaporation.
