The given figure shows the maxwell distribution of molecular speeds of a gas at three different temperature `T_(1),T_(2)` and `T_(3)`. The correct order of temperature is

Options

A. `T_(1) gt T_(2) gt T_(a)`
B. `T_(1) gt T_(a) gt T_(2)`
C. `T_(3) gt T_(2) gt T_(1)`
D. `T_(2) gt T_(3) gt T_(1)`

Answer

d

Explanation

At lower temperature, the molecules have less energy. Hence, the molecular speeds are lower, and distribution of molecules has smallar range. But as the temperature increase, distribution range flattens.
Hence, correct order is `T_(2) gt T_(3) gt T_(1)`
