Asample of gas occupies 9.0 ml at a pressure of 500.0 mm hg. a new volume of the same sample is at a pressure of 750.0 mm hg.

is the new pressure smaller or larger than the original?

therefore, is the new volume larger or smaller than 9.0 ml?

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
