Say I have an egg shaped plastic object filled with a gas and, say, 10% of its volume is filled with water and the gas is just normal pressure (1 ATM?). You can imagine roughly how easily the liquid rustles around inside if you were to move the egg.

Would the liquid move around as freely if the gas were to be under a much, much higher pressure? What would happen as the pressure of the gas increases? Assuming you could do this experiment without opening the egg or any real world problems i guess.

Thanks!!

How are you increasing pressure? It would make a difference. Are you increasing the density?

I am not doing your homework for you

Eventually as the pressure increases, the water will freeze, even at room temperature.

As the pressure increases even further, the ice will transition to one of the other isomers.

Shows how the viscosity of air (and other gasses) changes with pressure.

The important point is
"The impact of pressure is minor, and the viscosity correction for pressure is less than 10% for the gases in our calculation for pressures up to 500 psi (34.5 bar) (Crane, 1988)."
So the way the liquid sloshes wouldn't change much.

It wouldn’t be noticeable unless the pressure was VERY very high. Liquids are not very compressible. It would just slosh around.

Interesting, thank you!!

This answer covers everything. Thank you!

It might slosh less because higher air pressure means more drag.

It'd be very minor though, the velocities involved are pretty low.

Go grab a propane tank from the propane exchange and give it a slosh
Make sure you wear your science hat when you ask the nice lady at the customer service desk that you need to touch her tanks
