volume 440000ml = 440L [1L=1000ml]
increasing order of entropy is
1 mol of N2 in 390L ,< 1mol of N2 in 400 L< 1mol of N2 in 440L
entropy is a measure of randomness or disorder present in the system.greater the randomness greater is the entropy ,higher is the positive value of entropy and more spontaneous is the process
entropy depends on volume .more volume means more space for particles to move about ,therefore more is the chaotic movement, more is randomness so more is the entropy so the above trend occur because as we move from left to right volume increases ,in same trend will entropy increase
