the unit used to measure heat energy is called the ______.
the law that states that energy is never lost or gained, just transformed from one place or object to another is called the law of _________ of energy.
the measurement of how much heat/energy an object can hold per kilogram degree Celsius is called the ______ heat. the symbol given to this quantity is called ______.
water has a _____ specific heat. this makes is _____ to change the temperature of water compared to other substances.
the formula for specific heat is Q= mCp^T. this formula is used to measure transfers of ______.

the specific heat of water is ______ J/kgdegreesC
In this type of heat transfer fluid particles move from on location to another carrying energy with them.
In this type of heat transfer energy moves from atom to atom, but the atoms themselves stay in place.
Radiation is energy in the form of ________.
________ _________ colored material absorbs more energy than _______ colored material.
Dark, dull, light
Do you feel radiation?
No, because we can't feel light.

What is sea floor spreading? Where does it occur?
The earth spreading apart and rock comes up.
Under the sea.
Spreading apart as magma pushes up.
Formed when plates collide.
