We learned that heat can transfer to different objects and mediums three different ways: Conduction Radiation Convection: Warm air/liquids rise and colder air/liquids sink creating a cycle of movement. We know how energy transfers, but where does it go? We can't destroy matter, so technically, energy just goes...where? Earth has a nice atmosphere that is closed to the vastness of black space. So energy on Earth, stays on Earth. But energy can escape into space, so what happens to energy there? Well, in deep space, convection and conduction are nonexistent because gases are so far apart they can't touch, and the only place for a heat source to power convection would be a star...so basically the only energy in space is caused by radiation. Stars are powerful balls of plasma that spew radiation out into space. Studying heat transfer in space would be totally boring! Earth is the place to be if we want to watch energy transfer from different objects to different objects. So, is energy wasted in space? Is anyone worried about that? Wonder how much energy went into making that hair???

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
