Using words from the word boxes below. complete the paragraph about heat transfer, hot faster conduction warmer radiation more matter contact less convection transfer cold solid energy absorb vibrate fluid emit temperature 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 otherthings. This is known as Liquids andgases are different. Becausethesetwostates ofmatter flow, orare 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 Thisprocess is known as All objects give off, or some heat. All objects also take in, or heat.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
