hot less solid fluid conduction more convection energy emit warmer matter transfer absorb temperature 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. Identify the method of heat transfer that takes place in each illustration.

In the boxes below, draw an example of each type of heat transfer. Explain how heat is being transferred in your example. Conduction Convection Radiation Explanation: ________________ __________________________ __________________________ __________________________ __________________________ Explanation: ________________ __________________________ __________________________ __________________________ __________________________ Explanation: ________________ __________________________ __________________________ __________________________ __________________________ In each of the following situations, identify the method of heat transfer taking place. Write conduction, convection, or radiation on the line next to the statements. Choose the best answer. 1. You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer because of ______________________. 2. You buy a lava lamp from the store. As the lamp heats up, blobs of liquid rise to the top then sink back down to the bottom. This process continues because of ______________________. 3. You are doing your homework at a desk that is underneath a lamp. You start to feel hotter because of ______________________ from the lamp. 4. Your best friend has a bunk bed. You move from the bottom bunk to the top bunk and notice that the air is warmer. The warm air rises because of _________________. 5. You are in science class and want to see if the hot plates were used recently. You place your hand over the hot plate. Without touching the hot plate, your hand feels warmer. Heat is transferred to your hand by ______________________. 6. You are roasting marshmallows at a campfire.
