Heat Flashcards
Solid
A substance that’s atoms are tightly packed, and vibrating on the spot
Liquid
A substance that’s atoms are packed closely, vibrate and are free to move and flow
Gas
A substance that’s atoms aren’t bound together at all, are free to move around in straight lines
Kinetic energy
Energy of movement
Temperature
Average kinetic energy of the particles in a substance. Measured in C.
Absolute Zero
-273 degrees celcius
Heat
Sum of kinetic energy of particles within a substance. Measured in J (joules). Type of energy
Thermometers
Measure temperature
Conduction
Process of heat transfer by vibrating particles (solids)
Conductor
Substances that transfer heat easily
Insulator
Materials that do not conduct heat
Convection
Process of heat transfer by particles moving around, and denseness of different temperature substances. Occurs in liquids and gases
Radiation
Process of heat transfer by waves. Doesn’t occur in particles as such. Heat may be absorbed, reflected or transmitted,
