Changes in the phase of a substance (solid, liquid, gas)or formation/separation of mixtures of substances are common physical changes. TH. AND. CONGRATULATION. I . Mrs . Padmavathi. is going to take your . std. 10. th. Chemistry class.. May be this is the first time the class is commencing without direct Interaction with you all. I miss your laughing faces, curious questions during class. Hope very soon we meet and have real interactive class. .
