Homework Statement
Water contracts when cooled (at least above 4 °C). A beaker of water is cooled from 50 °C to 20 °C. The pressure at the bottom of the beaker increases.
Does the pressure increase or decrease as temperature decreases
The absolute pressure at the bottom of a cylinder filled with liquid is Pa=2.0 atm. The liquid is poured into another cylinder having half the radius. The absolute pressure at the bottom of that cylinder is Pa=5.0 atm.
I believe this is false.
Two cylinders are filled with water to the same height, but have different radii. The pressures on the bottoms of the cylinders are the same.
True - radii has no effect, just height?
