    while heating water from 0°C to 4°C range some of the hydrogen bonds between water molecules gets they come closer to each other and randomness decreases so entropy decr...

    This is because solid is less random than liquid which is tun is less random than gas .For the same state, at the same pressure, higher the temperature , greater is the randomness.
