Q. For free expansion of the gas which of the following is true
A) $Q = W = 0\ $and$\ \mathrm{\Delta}E_{int} = 0$
B) $Q = 0,W > 0\ $and$\ \mathrm{\Delta}E_{int} = - W$
C) $W = 0,Q > 0\ $and$\ \mathrm{\Delta}E_{int} = Q$
D) $W > 0,\ Q < 0\ $and$\ {\mathrm{\Delta}E}_{int} = 0$
Explanation
The correct answer is Option A: $Q = W = 0\ $and$\ \mathrm{\Delta}E_{int} = 0$.
