Heat/Energy Review
Question | Answer |
---|---|
Fahrenheit | The measurement unit for temp. used in the US |
Conduction | Heat transfer through solids-by colliding(direct contact, touch |
Radiation | Heat transfer through space |
Heat Mover | Moves thermal energy from one place to another |
Heat Engine | Device that converts thermal energy to mechanical energy |
Insulator | Material that heat does not flow easily through |
Potential Energy | Energy that is stored due to position |
Kelvin | Unit used to measure very cold temperature |
Joule | Unit used to measure energy |
kinetic energy | Energy of motion |
Conductor | Material that allows heat to flow easily |
gravitational Potential | Energy stored in object above the Earth's surface(rock on mountain) Ex: Apple falls out of a tree |
Law of Conservation of Energy | Energy changes form but none is lost-energy remains constant |
Absolute Zero | Temp where molecules slow to almost stop |
Sun bather | Radiation |
iron on clothes | Conduction |
soda can burns my hand | Conduction |
sitting near a fire | Radiation |
the current crated by warm air rising and cold air sinking | Convection |
Air rising up the chimney | Convection |
snow melting in your hand | conduction |
Nuclear fission | Nucleus splitting |
fusion | Nucleus coming together |
what is being created in a nuclear reaction | Energy |
what 2 factors determine potential energy | Height and mass |
what is the phase change called when a substance changes from a solid to a liquid | Melting |
Does the temperature increase during melting? What happens to the heat energy . | no, increases |
