Question

Which one of the following statements is not true about the effect of an increase in temperature on the distribution of molecular speeds in a gas ? (A) The area under the distribution curve remains the same as under the lower temperature (B) The distribution becomes broader (C) The fraction of the molecules with the most probable speed increases (D) The most probable speed increases

Tardigrade Admin · Accepted Answer

Distribution of molecules (N) with velocity (u) at two temperatures

T_{1}

and

T_{2} (T_{2} > T_{1})

is shown below :
At both temperatures, distribution of molecules with increase in velocity first increases, reaches a maximum value and then decreases.

Q. Which one of the following statements is not true about the effect of an increase in temperature on the distribution of molecular speeds in a gas ?

The area under the distribution curve remains the same as under the lower temperature

The distribution becomes broader

The fraction of the molecules with the most probable speed increases

The most probable speed increases

Distribution of molecules (N) with velocity (u) at two temperatures T1​ and T2​(T2​>T1​) is shown below : At both temperatures, distribution of molecules with increase in velocity first increases, reaches a maximum value and then decreases.

Distribution of molecules (N) with velocity (u) at two temperatures $T_{1}$ and $T_{2} (T_{2} > T_{1})$ is shown below :
At both temperatures, distribution of molecules with increase in velocity first increases, reaches a maximum value and then decreases.
