A small hole is made at the bottom of a plastic cup. If it is filled with water and allowed to fall freely, will waterfall down from the hole?

Yes, because of both gravity and the fact that nothing is obstructing the hole.

It depends on how big the hole is.

Explanation:

If the hole is too big, the water will fall freely out of the cup. However, if it is just a small opening (from a needle, pencil/pen tip, etc.) the water pressure will be able to hold in the water.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
