Is heating a wood splinter a chemical change and why?
Heating the wood (and not burning it) would be a physical change. If the wood splinter catches fire and burns, then it is a chemical change because a combustion reaction has taken place and the wood is no longer the same chemical composition. It will turn into carbon dioxide and water, and other materials left over.

Is heating and cooling are examples of a chemical change?
Heating can be due to a chemical change, for example burning a fuel is in effect a chemical reaction with oxygen. Also some chemical reactions are exothermic, ie they produce heat. Not so many produce cooling, but one is the combination of ice and salt.However heating and cooling happen for other reasons as well, so you can't say they are examples of chemical changes. It is correct to say that some chemical changes result in heating and cooling.
