I'm starting a Thermal Design course this semester and I need to come up with some type of thermal based design project. I came up with one idea, but im trying to determine its feasibility, which is not proving to be very easy. I have been trying to find the correlation between pressure, volume and temperature of a liquid in a closed container. So basically, I would have a container completely filled with a liquid (water). Then I would heat the container, which would cause the liquid to expand thus giving me a change in pressure in the container. What is the proper method to calculate the change in pressure? I'm assuming that the container is non-deformable. Thanks in advance.
