On increasing temperature, which of the following statement is correct? 

Options

A. area under `(dN)/(N)` vs V curve at different temperatures are different
B. fraction of the molecules having speed equal to decreases
C. more molecules possess speeds nearer to most probable speed
D. the distribution of speeds depends only on the value of molar mass of the gas

Answer

B, C

Explanation

a) as `T uarr` area under graph = no. of molecules remains same.
b) as `T uarr` fraction pocessing `u_(mp) darr`.
c) as `T uarr` more molecules possess speeds nearer to `u_(mp)`.
d) distribution of speeds depends on T also .
