Hello!
I have a problem : I have an elastic container (I call it "balloon"). I fill it 100% with water (no air bubbles) and close it. There is a pressure sensor connected to the balloon to measure the pressure inside it.
I would like to ask You : what factors have influence on the pressure inside the balloon, when it is lying on the table and no one is moving this?
I noticed that the pressure sensor says, that the pressure increases, when I heat the balloon a little (just a few C degrees) with a hair dryer. I was expecting that, but there is on thing I don't understand and I would like to ask about: When I left the balloon with water (and of course with sensor) for the night, the next day in the morning the sensor says that the pressure increased during night. But the temperature at night didn't increased - it decreased. I don't fully understand this, that is I would like to ask: what else could the pressure inside could be dependent on?
Thanks for help!
