Part A At what temperature is the rms speed of H2 equal to the rms speed that O2 has at 316 K? VO AEd T = KA cylindrical flask is titted with an airtight piston that is free to slide up and down, as shown in the figure (59%). A mass rests on top of the piston. Contained within the flask is an ideal gas at a constant temperature of 313 K. Initially the pressure applied by the piston and the mass is 100 kPa and the height of the piston above the base of the flask is 23.4 cm. When additional mass is added to the piston, the height of the piston decreases to 20.0 cm . V PartA Find the new pressure applied by the piston. Muest
