| Read the given statements and decide which is/are correct on the basis of kinetic theory of gases |
| (I) Energy of one molecule at absolute temperature is zero |
| (II) r.m.s. speeds of different gases are same at same temperature |
| (III) For one gram of all ideal gas kinetic energy is same at same temperature |
| (IV) For one mole of all ideal gases mean kinetic energy is same at same temperature |
A) All are correct
B) I and IV are correct
C) IV is correct
D) None of these
Correct Answer: D
Solution :
[d] Mean kinetic energy of any ideal gas is given by \[E=\frac{f}{2}T\] which is different for different gases. (f is not same for all gases)
