In the graph showing Maxwell Boltzmann distribution of energy ................ .

Options

A. area under the curve must not change with increase in temperature
B. area under the curve increases with increases in temperature
C. area under the curve decreases with increase in temperature
D. with increase in temperature curve broadens and shifts to the right hand side.

Answer

A, D

Explanation

Area under the curve must remain the same because sum of all fractions must be equal to 1, i.e., total probability is one. Hence, (a) is correct. Also (d) is correct and (b), ( c ) are wrong.
