NCERT Science Class 9 | Chapter 1 Part 2 | Evaporation

Why does pouring perfume on your hand feel cold? In the final part of our "Matter in Our Surroundings" series, we explore the magic of Evaporation and discover that there are actually five states of matter! In this video: Recap: We quickly review Solids, Liquids, Gases, and how they change states. Evaporation vs. Boiling: It's not the same thing! We define evaporation as a surface phenomenon that happens at any temperature. The "Drying Race" : We verify how Surface Area, Wind, and Temperature speed up evaporation. Cooling Effect: Why do cotton clothes keep us cool in summer? Why does water stay cold in a Matka?. Bonus States: Meet Plasma (the stuff inside stars!) and the super-cold Bose-Einstein Condensate (BEC). #evaporation #coolingeffect #plasma #boseeinsteincondensate #class9science #ncertclass9science #physicsfun #StudyTips #scienceexplained
