Febuary 3, 2011

We started class by checking our homework. We then started talking about 3 ways of heating. Which are, radiation, convection, conduction. Radiation is the transfer of heat through open space. Convection is the transfer of heat from matter to air. Conduction is the transfer of heat from matter to air.


We started looking at our simulation from homework. One example was a cup of coffee that had a little bit of particles. When the cup was hot the particles would speed up. When it was cooler, they slowed down. They all bounced off each other.


In our groups we discussed how a thermometer works. Mr. Finley asked us if you put a cup of coffee in the microwave and took it out then put a thermometer in it, what would happen? We learned that the energy of the hot water transfers to the glass particles which transfers its energy to the red stuff in the thermometer. Thermometer measures kinetic energy.

  1. I thought convection was the movement in fluids?!? I also thought convection, and conduction are different.

  2. Convection is the transfer of heat from matter through a fluid(liquid or gas; meaning air). Conduction is the transfer of heat from matter to matter. They are different.
