what would be the new pressure if 500 cm3 of gas at standard pressure is compressed to a volume of 250 cm3 (temperature and amount of moles is held constant)

1. if you have a gas at 127 degrees c, what is it's absolute temperature (kelvin)? a. 200kb. 300kc. 400kd. 500k2. if you had a gas whose absolute temperature measured 45 k, what is that temperature in celsius? a. -228 cb. -300 cc. 125 cd. 112 c

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.

The decimals you found in part b are called repeating decimals. in the gizmo, repeating decimals are rounded to two places. how does the gizmo show you that a decimal has been rounded?
