wick of a burning candle

raincoat exposed to rain

fabric of plastic umbrella in rain

tea spilled on glass slab

bristles of a paint brush in water

sponge pads used for cleaning vessels

milk in plastic container

wick of a burning candle

raincoat exposed to rain

fabric of plastic umbrella in rain

tea spilled on glass slab

bristles of a paint brush in water

sponge pads used for cleaning vessels

milk in plastic container

Explanation / Answer

1) Materials that show Capillary Rise are:

sponge pads used for cleaning vessels

bristles of a paint brush in water

wick of a burning candle

2) Materials that do not show Capillary Rise are:

raincoat exposed to rain

fabric of plastic umbrella in rain

tea spilled on glass slab

milk in plastic container

Reason: Capillary action is the momentum of H2O (or any liquid) through a narrow diameter tube. This force is determined by the molecular attraction between water and the absorbing substance. Adhesion is the attractive force between the liquid and other objects, which tends to move the water along the capillary. wick, sponge & bristles have narro diameter substances hence they will show capillary action. Plastic container, glass slab, fabric of plastic and rain coat (water repellant material) are broader diameter materials, they do not show this property.
