The burning of sauce on a stove is a chemical change. This is because the heat from the stove causes the molecules in the sauce to break apart and rearrange into new substances, such as carbon compounds and ash. This chemical reaction is irreversible and results in a change in the chemical composition of the sauce.
A wet handkerchief is a physical change. The water has only physically changed the state of the handkerchief by being absorbed, but the handkerchief itself has not undergone a chemical transformation.
it is not a change at all but putting pizza in the oven is a chemical change
chemical change. the dressing and mayonnaise changed completely to form the sauce.
Crystallization of the molecules. The substance is beginning to freeze.
The weight of a pallet of sauce can vary depending on the type of sauce, packaging, and quantity. On average, a pallet of sauce may weigh around 1,500 to 2,000 pounds.

The question to answer is "Has a new substance been created?" Most cdertainly heating does change the cheese, milk and eggs used in most mac and cheese recipes. So the answer is, yes, cooking mac and cheese is a chemical change.
Typically, very little to not at all. Tabasco sauce generally is at room temperature (293K), and you use very little of it. The "heat" in Tabasco sauce is all capsaicin, a compound that feels "burning" in your mouth, but does not have any physical heat.
No, the making of alfredo sauce is simply the combining of elements/ingredients. No chemical change occurs.
A physical change could be easily described as a change that you can reverse. Melting an ice cube, than freezing it, etc. Eating is actually both because you chew the food and swallow it. After that your stomach's enzymes dissolves the food and readies it for your digestive system. :D
Cooking hot cheesy pizza in the oven involves both physical and chemical changes. The physical change occurs when the dough rises and the cheese melts, altering their states but not their chemical composition. The chemical changes happen when ingredients like the dough and sauce undergo reactions during baking, resulting in new flavors and aromas. Overall, the process is a combination of both types of changes.
Only if you use it to stir the sauce regularly.
The alcohol is evaporated. That is not chemical. And it doesn't matter if the chef is french - in fact it evaporates even if the person making the sauce is NOT a chef.
physical change.
