Each of three identical 15.0-L gas cylinders contains 7.50 mol of gas at 295 K. Cylinder A contains He, cylinder B contains F2, and cylinder C contains Cl2. According to the kinetic molecular theory, which gas has the highest pressure? a. Cl2
b. Ne
c. F2
d. All have identical pressures

Define the kinetic molecular theory

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.
