Question

Why two holes are made in a sealed tin can to take out oil from it.

ICSE Class 9 Physics Chapter Pressure in Fluids and Atmospheric Pressure

Answer 1

Answer:

when one hole is made flow will be slow it is because tge air pressure enters same hole and when two holes are made the fow of oip is incresed and air pessure enters through that hole...hope it helps..mark it as brainliest

Answer 2

Dear Student,

◆ Two holes are made in sealed tin to take out oil because -

• If we make a single hole in tin can, pressure inside tin can becomes less than atmospheric pressure after some oil is removed.
• This negative pressure gradient prevents further removal of oil from tin can.
• Thus, an extra hole (total two holes) is made in tin can so as to maintain pressure inside can.

Thanks dear...
