Heat

  Hi today's blog is about Heat. Heat is very very important to us. It is what keeps us from freezing to death. Heat is someone or something warm.


 


 
       Heat can be transferred by radiation, conduction, convection. Radiation would be an exsample of electromagnetic waves so like the suns waves hiting Earth. Conduction would be transferd by molecular collisions. Convection would be transfer by circulation of a fluid.

       A conductor is something eletricly charged. Some objects are good and bad conductors like fur, feather, and plastic foam are bad conductors. Why you may ask well here is why fur and feather have no free electrons in there outer orbit they are busy doing jobs like being shared betwenn two atoms. Plastics, whose molecules are made from long combinations of carbon and hydrogen atoms, have few or no free electrons. This means that plastics are poor conductors of electricity

 Have you ever wondered why blankets keep you warm well here is why blankets keep you warm. They keep in your body heat to stay in the blanket so the warm feeling is your body heat.

. According to Nasa, when the temperature reaches 95F our work output drops by 45 percent.  On average, heat waves kill more people than any other natural disaster in the U.S. About 1,000 people a year die in the U.S. from the heat.The heat stored by roofs, pavement, and concrete structures can raise the night temperature in cities by as much as 22 degrees.
 

 

       OK that is all. I hope you liked the blog comment what you think and good bye everyone
