MOST PROBABLE SPEED

For a monotomic gas at temperature T, match the following columns. {:(,"ColumnI",, "ColumnII"),((A),"Speed of sound", (p),sqrt(2RT//M)),((B),"RMS speed of gas molecules",(q),sqrt(8RT//piM)),((C),"Average speed of gas molecules",(r),sqrt(3RT//M)),((D),"Most probable speed of gas molecules",(s),sqrt(5RT//3M)):}

Indicates the most probable sites for ArSE reactions.

If A and B are two events, the probability that at most one of these events occurs is

Statement-1. Most probable velocity is the velocity possesed by the maximum fraction of the molecules at a given temperature. Statement-2. On collision, more and more molecules acquire higher speed at the same temperature.

Assertion: Most probable velocity is the velocity possessed by maximum fraction of molecules at the same temperature. Reason: On collision, more and more molecules acquire higher speed at the same temperature.

If A and B are two candidates seeking admission in an engineering college. The probability that A is selected is 0.5 and the probability that both A and B are selected is at most 0.3. Is it possible that the probability of B getting selected is 0.7 ?

Aa n dB are two candidates seeking admission in ITT. The probability that A is selected is 0.5 and the probability that Aa n dB are selected is at most 0.3. Is it possible that the probability of B getting selected is 0.9?

Aa n dB are two candidates seeking admission in IIT. The probability that A is selected is 0.5 and the probability that Aa n dB are selected is at most 0.3. Is it possible that the probability of B getting selected is 0.9?

Aa n dB are two candidates seeking admission in ITT. The probability that A is selected is 0.5 and the probability that Aa n dB are selected is at most 0.3. Is it possible that the probability of B getting selected is 0.9?

The RMS velocity of the molecules of a gas is greater than the most probable velocity at the same temperature.
