Oil increase in pressure

[gtsolid]

Hi everyone,
In a constant volume chamber i have a starting p_0. If i give heat and the temperature increases of 50°, how does the pressure vary?
If i had a gas, i can suppose it as ideal and apply the Ideal gas law. But considering a liquid, how can i do?

Try this.

Basically it's the bulk modulus of the fluid that you're after if your chamber truly is constant volume.

Real life says it isn't and even the smallest amount of gas in the volume makes a huge difference.

An increase of 50C with no volume expansion could be in the hundreds of bar increase
