Then, water with impurities can be removed by decantation. Evaporation is also known as vaporization. • Precipitation - When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs. That would mean that it would be harder for a phase change, so the evaporation rate would be slower. 2. At the evaporative surface, there is a continuous exchange of liquid water molecule into water vapor & vice versa. Question 8.

Heat can turn a liquid into a gas and cooling can cause a gas to turn to a liquid. a. Sedimentation 1. Several factors affecting the evaporation are temperature, surface area, agitation, atmospheric aqueous vapor pressure,wind. We will separate sand and water by using sedimentation and decantation method First we have to leave this mixture for some time After some time, the sand which is heavier settles down at the bottom. 2nd PUC Model Question Papers with Answers, 1st PUC Model Question Papers with Answers, KSEEB SSLC Class 10 Social Science Solutions, KSEEB Solutions for Class 9 Social Science, 2nd PUC English Previous Year Question Paper June 2018, 2nd PUC Statistics Question Bank Chapter 3 Time Series, 2nd PUC Statistics Question Bank Chapter 1 Vital Statistics, 1st PUC Economics Question Bank Chapter 6 Measures of Dispersion, 1st PUC Economics Question Bank Chapter 5 Measures of Central Tendency, 2nd PUC Question Banks with Answers Karnataka, 1st PUC Question Banks with Answers Karnataka, KSEEB Solutions for Class 9 Karnataka State Syllabus, KSEEB Solutions for Class 8 Karnataka State Syllabus, KSEEB Solutions for Class 7 Karnataka State Syllabus, KSEEB Solutions for Class 6 Karnataka State Syllabus, Karnataka SSLC Model Question Papers 2020-2021 with Answers Pdf KSEEB Class 10, KSEEB SSLC Class 10 Solutions Karnataka State Syllabus, To separate harmful or non – useful substances that maybe mixed with it, To seperate even useful components if we need to use them separately. 5) Atmospheric pressure on the liquid under evaporation: The rate of evaporation is inversely proportional to the atmospheric pressure on the liquid under evaporation. Evaporation is a process by which water is converted from its liquid form to its gaseous form.The Process of converting water vapor into water is called cond.
