Question

What’s the answer for part 2)?

I tried using the formula:

1/2 x m x v^2 = 3/2 x Kb x T

Question: A cylinder with a cross sectional area of 48.28 cm2 is sealed with a piston that is free to move (Figure th. the piston is initially a height of 11.91 cm above the base. The pressure inside the cylinder is 1.05 atm. The gas in the cylinder is at 29.3 C The cylinder is filled with N2, which has a molar mass of 28.01 g/mol Free to move 2 Diagram not to scale 1: Schematic representation of the conta r the described conditions sealed with a movable piston

Answer 1

V_rms = squareroot 3 R T/M = squareroot 3 times 8.31 times (273 + 29.3)/28.00 times 10_-3 = 518.7 m/s
