Thermal Energy Transfer - Conduction, Convection, Radiation Patterns of Thermal Energy

Heat is a measure of thermal _ energy waves radiation light Match each word with its information. energy transfer movement of energy from one place or object to another thermal energy the total energy of all the moving particles in an object (heat energy) temperature a measure of heat, the average kinetic energy of the molecules predictable patterns expected: heat always transfers from a warmer object to a cooler object. Heat travels by conduction when objects are - far apart circulating in contact with one another gases As temperature increases, the molecules that make up a substance _ slow down stay the same speed up break apart Match It! Match each word with its information. conduction the transfer of heat from one solid substance to another solid that it is touching. convection the transfer of thermal energy by liquids or gas radiation the transfer of energy as electromagnetic waves, does not need to be touching anything to transfer heat. equalization occurs when objects reach the same temperature (equal) In this image, heat is traveling by - conduction convection radiation evaporation When objects of different temperatures are touching, heat will move from one object to the other by - conduction convection radiation combustion A microwave oven works by _ of heat so that the food is heated from the insideto the outside. conduction convection radiation evaporation The pot becomes hot due to the transfer of heat by - _. conduction convection combustion radiation Fill in: Heat Transfer Click on each dot and fill in the blank with the type of heat transfer. Use only lower case letters or copy and paste from the word bank.Word Bank: conduction convection radiation convection conduction radiation Sort it Out! Classify each example of heat transfer Conduction a spoon gets hot while stirring a cup of hot tea you burn your finger on a curling iron a candle flame melts the wax of the candle Convection hot air from a heater circulates in a room ocean waters move heat from place to place hot air rises Radiation heat from a bbq pit can be felt when hands are held above it the sidewalk becomes very hot on a summer day a solar panel becomes warm as it collects light energy Jennifer left her popsicle sitting on a plate to watch it melt. How is thermal energy moving in this scenario? cold to hot hot to cold hot to hot cooler to warmer The measurement of how fast the molecules in an object moves is known as- movement energy temperature volume Which of these objects is a conductor of heat? wool copper glass cloth Which sentence explains why a cold metal spoon placed in a pot of boiling water becomes hot? Thermal energy is transferred from the spoon to the water. Thermal energy is transferred from the water to the spoon. The spoon falls in the water. Cold can never move into something, it is _ flowing out that makes us feel cold. cool air heat atoms moisture If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL _. one reaches a temperature of 0° C. they reach an equal temperature. one runs out of energy. one is absorbed into the o Hot water is added to a bathtub containing cold water. After a few minutes, what will happen to the water in the tub? the hot water will float on the top the hot water will begin warming the colder water the cold water will float on top of the hot water the cold water will get colder and the hot water will get hotter Which of the following is TRUE of the diagram shown above? it shows the pattern that heat flows most of the time it shows the pattern that heat flows some of the time it shows the pattern that heat flows all of the time none of these are correct
