Heat Transfer
What is heat?
Energy is transferred between objects?
Name two good insulators
Glass, plastic, oil, dry wood, rubber and diamond are all correct answers
Energy is...
The ability to do, work, or make something move or change in some way.
Conduction is...
Energy transferred through direct touch?
Name three good Conductors
Silver, gold, copper, steel, and seawater are all correct answers.
Chemical Energy is...
0 energy that is avalible for release for chemical reactions.
Radiation is...
Energy transferred through empty space?
Why are car wheels made of rubber?
Because if lightning hits the ground, the rubber stops it from traveling up to the metal part of the car.
Thermal energy is...
Is heat energy. The heat energy of an object determinds how active its atoms are.
Convection is...
Energy transferred through (ONLY) Liquids and gasses?
Why would you get electrocuted if you touched a metal power cord?
The metal would let the electricity move easily through it, and without rubber or plastic to keep the electricity in, your skin would get zapped.
Electromagnetic Energy is...
Is 0 light energy, energy 0 includes energy from gamma rays, x-rays, ultraviolet rays, visible light, infared rays, microwaves, and rasio bands.
BONUS! What is the second law of thermodynamics?
It says that thermal is always moving from the hottest object to the coldest.
BONUS! Is Titanium a good conductor of electricity?
NO! Titanium would have a conductivity of 3.1%, which means it is 97% worse of a conductor of electricity than copper, which has a 100% conductivity percentage.
Mechanical Energy is...
Is 0 energy due to an objects motion (kenetic(Now moving) or position. (potintial(Could happen)
