All the Best! 1 / 10 Conversion of solid directly to gas without becoming liquid is: fusion condensation freezing sublimation 2 / 10 At constant pressure, increasing temperature of gas causes volume to: decrease increase remain constant vanish 3 / 10 Two identical wet clothes are dried—one under a fan and one in still air. The faster drying under the fan is mainly due to: lower humidity removal of water vapour layer higher pressure condensation 4 / 10 A gas cylinder feels cool when gas leaks because: condensation absorbs heat melting occurs evaporation absorbs heat pressure increases 5 / 10 Sweat cools our body due to ______. freezing melting evaporation condensation 6 / 10 Ice floats on water because solid water: has higher density has lower density absorbs heat has no attraction 7 / 10 Compressibility is maximum in ______. gases solids liquids ice 8 / 10 Higher wind speed increases evaporation because it: removes water vapour near surface decreases surface area increases humidity lowers temperature 9 / 10 During freezing of liquid, particle kinetic energy: increases decreases remains same becomes maximum 10 / 10 The process of gas converting into liquid on cooling is: sublimation deposition evaporation condensation Your score is 0% Restart quiz
