Question 26 28 SapiingLearning The graph tothe right is the distribution ofthe number of gas molecules, Nar compared to the molecular speed, u, for gas Aand gas B. Identify curve A at the conditions specned A and Bare different gases at A and B are the same gas at the same temperature.

Explanation / Answer

MW of He = 4 g/mol

MW of N2 = 28 g/mol

now..

curve A is most likely N2, since it will have most of molecules at LOW velocities (u is velocity)

now

expect higher velocity at high T, therefore for 1400 K, this will be the read value

at low T, i.e. 700K, this will be the "A" Curve

Q2.

point 1 is the MOST probable speed, since most moleucles hav ethis, i.e. it is the maxima

thjen

the RMS; root mean square speed is the 2nd point, which accounts for the "infiinity" value in the x-axis
