What is the main difference in physical state between dew and frost?

Answer and explanation

Correct answer: Dew is liquid and frost is solid (ओस तरल है और पाला ठोस है)

Correct answer: B. Dew consists of liquid-water droplets deposited on a cool surface. Frost consists of solid ice crystals that form when the surface is sufficiently cold and water freezes or water vapour changes directly into ice. Thus, both are related to moisture and cooling, but their physical states are different: dew is liquid and frost is solid. Option A reverses the states and also incorrectly calls dew a gas. Lava is molten rock, so option C is unrelated. Dust is made of solid particles of soil or other materials, but it is not condensed atmospheric water, so option D is also wrong. Memory cue: dew = drops; frost = ice.
