Can you put more concrete on top of old concrete?
Yes, if the base is stable the new layer will bond and create a new, fresh surface.An unstable base will give bad results. You should pressure wash the old concrete to get rid of loose and spalling concrete and you should use a bonding agent to serve as a primer to get the new layer to bond well to the old.Obviously, if the new concrete is laid over concrete that is subsiding because of a sinking foundation, the new concrete will crack. You need to stabilize the old concrete before pouring new over it.If you put new over old, it needs to be at least a couple inches thick else it will not cure properly. If you simply want to improve the surface, there are special self-levelling concrete mixes that can be poured thinner and still be strong. Take a look at the link below for a good how-to.

Is a chalk grinding a physical change?
It doesn't matter if something is reversible or irreversible. it will not depend if it is a chemical or physical change. A physical change is when the composition of a substance remains unaltered (the particles stay the same) and no new substance is produced. Such as when you make a paper plane out of paper, the appearance changed, the particles stayed the same, no new substance was created, and the paper remains paper. A chemical change is when the composition of a substance is altered and a new substance is produced. Such as when paper is burned, the new substance produced is the carbon and other gases from the fire, and the composition of the paper changes, slowly disappearing.It usually is unless you draw so rapidly that the heat of the friction heats the paper and causes it to smoke.
