(A) Convection involves flow of matter within a fluid due to unequal temperatures of its parts.
(B) The change of solid state to vapour state without passing through liquid state is called sublimation.
Based on above information, pick correct option.
Solution:
Statement A is correct as thermal convection is driven by density variations arising from unequal temperature distributions in fluids. Statement B is also correct as sublimation is the direct phase transition from solid to gas.
