Water is considered a polar molecule because it . a. has the ability to freeze. b. is made up of hydrogen and oxygen. c. has a partial positive and negative charges at each end

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
