So remember that radiation means electromagnetic waves going from one object to another. So an example would be holding a pot over a stove or a fire. It heats up the object. Conduction is heat touching something. So an example of that could be you touching a really hot oven or pot handle. And convection is when warmer air or liquid rises. So an example would be water boiling inside the pot. Hope this helps and if it does would you mind giving brainliest please. Luv you girly
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
This process is not reversible and a change of energy that is sometimes heat is given off.
