What is a type of material that keeps heat out of a shed during summer?
- steel, wood, copper, aluminum
wood
What does a thermometer do?
measures the amount of heat
If a barn is being build to keep it cool in summer and warmer in winter, which is the better choice. WHY?
- wood, metal,
Wood because its the better insulator and does not conduct heat well. it will keep the heat out in summer but keep the inside warm during winter
What is Radiation?
The transfer of heat without matter to carry it.
Name an example of mechanical energy turning into electrical energy
Wind Turbine, water turbine, generator
Name an example of a good insulator
name an example of a good conductor
wood, rubber, air,
metal,
If a snake sits in the sun to get warm, what type of energy transfer is taking place?
- sound, electric, thermal, mechanical?
Why does the end of a spoon sticking out of a hot pot still get warm?
Heat will move from warm to cool objects. over time the handle will heat up.
