How Does Temperature and Pressure Affect Water Density?

[dillonmhudson]

Homework Statement

"A steel cylinder of mass 2 kg contains 4.0 L of liquid water at 25 degrees centigrade at 200 kPa. Find the total mass and volume of the system."

Homework Equations

I know that water at 4 degrees centigrade is approximately 1000 kg/m^3. But how about when it is pressurized and at 25 degrees centigrade?

The Attempt at a Solution

I don't know where to start with this one.

Thanks for any help.

You typically have a table or chart in your textbook which has the required info.

 

[dillonmhudson]

The questions are not from the textbook so the tables do not provide the required information.

You could start here: http://en.wikipedia.org/wiki/Properties_of_water

Already been there. Didn't find anything.

Try this chart, you might find a better one elsewhere:

To solve the problem:

What is the water density and, therefore, the water mass ?
Can you now tell the combined mass ?
What do you have to know to estimate the volume of the steel cylinder ?
Can you approximate the steel cylinder height and inner diameter ?
What about the outer diameter ?
What will be the combined volume ?
