www.ncert.nic.inProperties such as shape, size, colour and state of a substance are called its physical properties . A change in which a substance undergoes a change in its physical properties is called a physical change. A physical change is generally reversible. In such a change no new substance is formed . Let us now consider the other kind of change. 6.2 ...
