JOSH METER? a, b and c show the magnified schematic pictures of the three states of matter. The motion of the particles can be seen and compared in the three states of matter. atoms ke beech ka distance ∝ motion of atoms “matlab agar jyaada distance hua to space jyaada hogi atom ke paas yaani jyaada jagah hogi motion ke liye” Sublimation: The change of the solid state of the matter directly on heating to vapor state (without becoming liquid) is called sublimation. The substance is dry ice, Naphthalene balls (mothballs, Iodine, Ammonium chloride, etc.) Example: When camphor or ammonium chloride is heated in a China dish covered by a inverted funnel (with cotton plug in its upper open end), the vapours of ammonium chloride are converted into solid ammonium chloride on coming in contact with the cold inner walls of the funnel. SUBLIMATION solid gas “Sub li” mation - Subtract Liquid phase Liquid nahi banega! isse samajh lo! “Class 9th Phodenge” - Prashant Bhaiya
