Homework Statement

3. The water volume of the central heating system at 10 º C is 0,800 m3 . (a) What is the volume of water flowing out from the overflow pipe when the system temperature rises to 60 ° C. The coefficient of volume expansion of the water is 2,1 × 10-4 1 / K? b) How does the answer change when you also consider the thermal expansion of the system made of steel? The coefficient of volume expansion of steel is 35,1 × 10-6 1 / K.

Relevant Equations

pv=NRT

I don't know what formula to use to figure that out,help

Don't double post
read the guidelines
make an effort; "don't know" is no good in PF
"The coefficient of volume expansion" makes a much more useful equation than pV= NRT
