PHYSICAL AND CHEMICAL CHANGES Boiling the water was a physical change because the

liquid was turning into a gas but they are still H20 molecules.

Adding the noodles to the water was a physical change. Draining the water from the noodles was a physical

change. Adding the ingredients to the noodles was a physical

change. Stirring the ingredients is a physical change also. Chewing the macaroni and cheese is a physical change but digesting it is a chemical change.

CHOICE OF POT I chose a medium sized pot because it

cooks faster than a large pot and can hold more water. There were no cons.

LAW OF CONSERVATION OF MASS The law of conservation of mass was applied

here because I started with 3 cups of macaroni noodles and then after I boiled them and added the ingredients I still had 3 cups of macaroni.

Some mass was lost when the water boiled because it evaporated and turned into a vapor.

ENERGY TRANSFER As you add heat to water, its temperature

increases... until you reach the boiling point. Then, as you add heat, the temperature stays the same until the water is completely boiled off.

Heat was transferred fromthe boiled noodles to the Ingredients to help melt them.

THE LAW OF CONSERVATION OF ENERGY This law was demonstrated by me

putting energy into the cooking of the macaroni and cheese and I got energy in return after I ate it.

INTERMOLECULAR FORCES Before I made the macaroni and cheese

the water was a liquid and liquids have medium intermolecular force.

After I made the macaroni and cheese and added all the ingredients it became a solid and solids have high intermolecular forces.
