A and B are two unknown elemental gases in two separate containers. A has a higher molar mass than B . Which of the following statements is true?
a)
The average kinetic energy of A is greater than B
b)
If A and B are at the same temperature, urms,A = urms,B
c)
If A and B are at the same temperature, urms,A > urms,B
d)
If A and B are at the same temperature, the average kinetic energy
of A = the average kinetic energy of B
e)
The average kinetic energy of A is less than B
Homework Answers
Avg Kinetic energy = 3 * K * T / 2
K is Boltzmann constant, T is temperature in Kelvin.
Thus, Avg KE is dependent on temperature.
In given scenario, temperature is same.
So,
A and B are at the same temperature, the average kinetic energy of A = the average kinetic energy of B

A and B are two unknown elemental gases in two separate
containers. A has a higher...
