Question

From which container will the liquid will evaporate first plate cup or glass

Answer 1

Plate bcoz it has has larger surface area

Answer 2

plate. this is because the rate of evaporation depends on certain factors. the surface area is one of the factors. larger the surface area, greater will be the rate of evaporation. in your case, the plate offers larger surface area. more molecules will evaporate simultaneously. hence the liquid will evaporate from plate first. hope it helps. :)
