Tin Foils Lab Report

The materials I used for this experiment were foam, duct tape, tin foil, yarn, cardboard, and a tin can. My idea came from the idea of a cooler because of the inside foam insulation. I got the idea of the duct tape when I thought about air ducts and how they wrap them in duct tape to repair them, and how you can't feel the heat from the ducts. I got the Idea for the tin foil, because tin foil is used for baking. I got the idea for the yarn because I thought it would be good insulation for a top because cotton is a good insulator and cotton is like yarn. I got the Idea for the cardboard because I thought it would be good for a top cover to keep the heat of the beverage in the insulated container.

My first material, rubber, is a good insulator, because it doesn't conduct heat because the valence electrons are 4 and so join with other molecules to make strong bonds. and when you

and when you add impurities you have free electrons or holes that make it a (poor) conductor. It prevents radiation, because it prevents electromagnetic waves, it also prevents conduction, because it doesn’t conduct heat, so it cannot transfer heat to objects. It prevents convection, because the atoms cannot move through the water in the object.

My third material, yarn, is a good insulator, because it doesn’t conduct heat, because the valence electrons are 4 and so join with other molecules to make strong bonds. and when you add impurities you have free electrons or holes that make it a (poor) conductor. It prevents radiation, because it prevents electromagnetic waves, and it prevents conduction, because it doesn’t conduct heat, so it cannot transfer heat to another object. It sometimes prevents convection because the atoms in the air or water can travel through the yarn if it comes in
