is it right that ideal gas only obey the boyles law under high temp and low pressure?
"Ideal" means PV = n R T
If it does not obey the simple gas laws, it is not "ideal".
so how about this question?
Which of the following desceriptions about ideal gas is/are correct?
1)An ideal gas obeys Boyle's law only under high temp and low pressure
2)the molecules of an ideal gas have no size
3)the internal energy of an ideal gas consists of kinetic energy only
THE ANS IS D but not 1,2,3 are correct,why?
