Based on the distributions show above, which of the following are true statements for the three gases I II and III ?
Note that the temperature is constant

a) gas III is the lightest of the three gases

b) the most probable speed of the molecules of gas II
is greater than that of the molecules of gas III

c) all the molecules of gas III have an actual speed that is greater
than those of gas I

d) plots of the molecular kinetic energy distribution for the three gases
would all be identical (superimposed on each other)

e) increasing the temperature would increase the most probable speed
of the molecules of each gas

Answer 1

a) gas III is the lightest of the three gases--True.

b) the most probable speed of the molecules of gas II
is greater than that of the molecules of gas III--False.

c) all the molecules of gas III have an actual speed that is greater than those of gas I--False.

d) plots of the molecular kinetic energy distribution for the three gases would all be identical (superimposed on each other)--False.

e) increasing the temperature would increase the most probable speed of the molecules of each gas--True
