Question
There are two containers, A and B , of equal size. Gas that behaves ideally is in both containers and it is known that A has a temperature of 52ºC and B a temperature of 9.0ºC. Nothing else is known about the gasses. Which of the following statements must be true? Which could be true? (a) The pressure in A is higher than in B . (b) There are more molecules in A than in B . (c) A and B cannot contain the same type of gas. (d) The molecules in A interact with each other more than those in B interact with each other. (e) The molecules in A have more average kinet- ic energy per molecule than those in B . (f) The molecules in A are moving faster than those in B . Explain your reasoning behind your answers.
Explanation / Answer
here,
the true statements are;
(e)
The molecules in A have more average kineteic energy per molecule than those in B
f)
The molecules in A are moving faster than those in B .
kinetic energy of a molecule = 1.5 k * T
rms speed = sqrt(3 *k * T/m)
k is blotzmaan constant
