How Does Water Volume Affect Pressure in a Closed Container?

[Physicist1011]

Homework Statement

A closed container is connected with a tube, water will enter the container via this tube. How would the amount of water in the container affect the pressure in it when water enters the container via the tube?
Is this the same as changing the volume of the container (which water is being poured into (by a tube). If so how does a smaller container volume affect the change in pressure when water enters the container via tube?

You seem to only have given the question without any supporting equations we would need to know or an attempt at the solution.

Could you please give some more information and follow the homework question format?

No equations involved. I don't understand how changing the volume of water in the container (to start with there will be a volume of water in the container) will affect the pressure increase in the container when water enters it via a tube. And also if this is the same as using a smaller container, how will this effect the pressure increase in the container if a smaller container is used?

I think I understand what you're saying. If you have a sealed box, with air in it. The amount of air is constant and has a constant density and fills up the box. You then proceed to add water to the box through a tube which I'm assuming acts like a valve and only let's in water but does not let out air.

Now, think about this. There was a fixed amount of air taking up the entire box and you just added some water. Where is the place for the water? Only option is for the pressure and subsequently the density of the air or water to increase so there is more place.

Smaller the container, less place, so more pressure.

Is this what you wanted?

Yes, thank you.
