You may use Charles Law to show a physical modify in an ordinary bar of Ivory soap.

Charles Law states that a gas based material has a continuous pressure and if the temperature increments so will the gas and if a bar of soap is made of foam this must cause the foam to increase in size because it is made of cell based gas molecules and will also increase in size.

Let us look at this before we proceed.

Soap is a foam. Foam may be any material that has trapped gas inside of it, more or less like tiny bubbles. You may not think of soap as a foam because it is solid and hard but foam may come in numerous forms and they may be solid, hard or soft and spongy. You probably think of whipped topping as a foam as well as foam you use to shave.

We are going to test increasing the temperature on a bar of Ivory soap to see if the gas inside of the foam will cause the soap to exaggerate and cause a physical change.

Here is what we need.

1. A bar of Ivory Soap

2. A paper plate

3. Another bar of soap; not Ivory

Now unwrap the Ivory soap and place on the paper plate.

Microwave the soap and watch it almost while it is cooking to see what happens.

Your soap must finish cooking in 1 to 2 minutes. This all depends on the temperature of your microwave. If you cook it too long the soap will not get any bigger.

Let the soap cool off before removing it or touching it. You may want a parent to support you with this so no one gets burned.

After the soap is cool touch it and thoroughly examine it. The soap it flaky and hard. It is still soap and you may wash your hands with numerous of the flakes.

Why does this work?

Well, when you cook the soap it makes it soft and you are boiling the water and gas that is whipped inside of the soap. When you boil water it evaporates and as it heats likewise expands. When water turns to gas it elaborates and this causes the soft portions of the soap to likewise exaggerate and makes it now actually look like a foam.

When you cook the soap there is a physical alter but no chemical change. It is still soap. This is likewise why Charles Law is shown because the volume of gas increase as the temperature increases. The microwaves from your oven excite the energy molecules in the soap and cause them to move very fast and when they do this they move away from each other as they bounce off each other.

If you undertake another brand of soap, you will probably find that it puffs galore but basically melts because a lot of other soaps do not incorporate the same amount of air. I do not commend cooking another kind of soap as a heap of have a large total of perfumes that have strong odors when they are being cooked.

This is why a bar of Ivory soap will float equated to other brands of soap. It has more air whipped into it is preparation and just like a kid with a float on their arms full of air that causes them to float in a swimming pool, a bar of Ivory soap will float because it has lots of air packed inside. Test another brand of soap to see if it will float. Now cut the Ivory soap in half and look at it. Do you see the little holes of air? Look at another bar of soap after cutting in half.

When doing this science project:

Stay at the microwave and do not leave it unattended.

Do not put metal items in the microwave
This will not hurt your microwave or the soap. You may still use the soap when done.
You will detect an odor from the soap as it is cooking. This will make your microwave smell fresh and flowery for a few hours. Only use Ivory soap.
