What are some examples of chemical and physical changes in heat taking place around you for one day?
One example of chemical change is lighting a gas stove to cook material. That is the oxidation of methane.
CH4 + 2O2 ==> CO2 + 2H2O
Cooking is another example of chemical change; for example, baking bread.
One example of a physical change is one suggested by Cathrine.
Thanks. Is the oxidation of methane exothermic or endothermic?
All oxidations are exothermic
Melting ice: physical change
Yes, melting ice is a physical change.
