Question
The graph which represents the variation of mean kinetic energy of molecules with temperature toC is :-
Options
A.
B.
C.
D.
Solution
Mean kinetic energy of gas molecule
E =
kT = 
k(t + 273) = 
t + 
× 273k;
Comparing it with standard equation of straight line y = mx + c. We get m =
k and c = 
273k
So the graph between E and t will be straight line with positive intercept on E-axis and positive slope with t-axis.
