Question 1: Why are metals good conductors of heat? Metals are good heat conductors. I will explain why. Inside a material, there are nucleus and electrons. The electrons are attracted and stay with the nucleus. In metal, the electrons aren’t attracted to the nucleus. It is like this in all metal. The free electrons are free so they speed up and whizz around. They collide with the atoms getting warm. It is like a domino effect. They warm up each other once they collide. It is so fast that heat can be transferred up metal in no time.
Question 2: Why does hot water and air rise? Hot water and air rise when they are being heated. The reason why is because the heat make the air and water less dense. The correct term for this is “the buoyancy principle.” Just imagine you have a cork and put it into a glass of water, since it is light and is less dense than water, the force pushes it up and the cork floats. The exact same thing happens to the air and water in this case.
Question 3: How is heat transferred from a campfire to you? Heat is transferred from a camp fire to you and me by convection. The way it works is when an object is warmed up, it causes the molecules above it to speed up. The hot air turns less dense, then the air is conveyed up wards.
Conduction Similarities: This essay will explain the similarities of Conduction and Properties of Matter. In a few of our properties of matter labs, we were dealing with a stove or something else to warm up water. We were warming up and boiling water for different experiments. The way that conduction and properties of matter labs were similar is that when boiling the water. The water gets really warm. The heat makes the glass beaker or plastic beaker warm. The nucleus’s and electrons heat up and bump into each other creating the domino effect. The beaker got too warm so we needed gloves in order to move it around.
Convention Similarities: This essay will explain the similarities of Convention and Properties of Matter. In some of the labs, we were dealing with heat. We boiled and heated up water. Convention took place during our experiments. The way it worked was that once the water was warm and about to boil, there was steam rising from the beaker. This is when the air above starting heating. The molecules were expanding and getting less dense. The heat was then transferred. When we put our hands on top of the beaker, we could feel the heat. It was really warm.
Radiation Similarities: This essay will explain the similarities of Radiation and Properties of Matter. When we were boiling the water in some of the labs. We could feel the heat. The heat was transformed by heat waves, know as radiation. We were standing a distance away from the boiling water, but we could feel the warmth. The heat travelled through heat waves and ended up warming us up. You can see heat waves on a really sunny day, if you stay close to the ground and look across a flat surface, you can see the waves.
