Consider the following statements:

ISRO has invented the first patented capillary cup to drink liquids in space for astronauts.

Capillary action occurs when the adhesion between liquid and solid is lesser than the cohesion of the fluid.

The narrower the tube, the capillary action is also more.

Which of the statements given above is/are correct?

Question

NASA has designed a super cup to drink liquids in space for astronauts.
The cup functions based on combination of surface tension, wetting and cup geometry to keep the liquids in place.
The porcelain ceramic version of the cup was designed on the International Space Station.
It is the first patented product invented in orbit.
Capillary action is the movement or flow of liquid through a narrow tube using surface tension.
It occurs when the adhesion between liquid and solid is greater than the cohesion of the fluid.
The narrower the tube, the capillary action is also more.
