radiation contact cold vibrate waves
All _____________ has heat. Heat is a form of __________ caused by particles in an object that
_______________. The _____________ the particles of an object vibrate, the _____________ the object
will be. Because particles of an object are always moving, heat __________ is always happening. Heat always
flows in the same direction: from ______ to ______. Heat transfer will stop once two objects reach the
same _____________________. This is known as equilibrium.
There are three key ways that heat transfers. With ________ objects, heat transfers when the objects come
into direct ____________ with other things. This is known as __________________. Liquids and gases are
different. Because these two states of matter flow, or are ___________, heat transfer happens when
warmer, _______ dense particles rise and cooler, ______ dense particles sink. This ongoing process is
known as a _______________ current. Heat can also be transferred through space (distance) in the form of
_________. This process is known as ___________________. All objects give off, or _______, some heat.
All objects also take in, or ________, heat.
