A 1.1 L balloon filled with gas at ground level (troposphere) experiences a pressure of 755 torr, as the balloon rises into the upper mesosphere the balloon swells to 8.75 L until it finally bursts. What was the pressure (in atm) exerted onto the balloon before it bursts?

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.
