Today, we went over homework and took the science quiz scheduled for yesterday. The homework was to find 3 types of heating. Here are the three types:
Conduction is the transfer through matter from particle to particle. Conduction is most effective in solids, but it may occur in fluids. An example of conduction is a spoon in some hot soup. The spoon becomes warmer becomes warmer because the heat is conducted along
the spoon. Another example of conduction is when you touch metal. When you touch a metal spoon, it usually feels colder than you. The metal spoon is not colder though. It only feels colder because it conducts heat away from your hand.
Radiation is electromagnetic waves that transport energy directly through space. An example of radiation is sunlight. Sunlight moves directly through space to Earth, without help from any fluids or solids. Another example of radiation is a light bulb. The closer your hand gets to the light bulb the warmer it feels. The light bulb is emitting heat without any help from fluids or solids, like sunlight.
After we reviewed this, took our density quiz.
