Heat transfer-notes-Questions and Answers Graded A+ Heat - ANSWER-___ is the transfer of thermal energy between objects with different temperatures. Thermal energy - ANSWER-___ is energy in form of heat. Warmer object to a cooler, Warmer objects have more energy than cooler objects - ANSWER-Thermal energy travels from a ___ ___ ___ ___ ___ object. ____ ___ ___ ____ ___ ___ ___ ___. (Energy from a stove burner flows through the pot and into the water causing it to get hot. Not from the water to the burner!) Heat transfer, three, conduction, convection, radiation - ANSWER-___ is the way heat moves through one object to another, there are ___ ways heat can transfer between objects. They are: ___, ___, and ___. conduction, directly from the hotter object, directly into the cooler object - ANSWER-__ is the transfer of thermal energy from one object ____ into another. (direct contact). If an object is touching a hotter object, thermal energy will flow ___ Example: A pot touching a hot burner, a metal spoon in a hot cup of coffee, a snowball in your hand. Convection, movement, gas, warm up and rise, gap, cooler molecules, warm and rise too, convection engine - ANSWER-___ is the transfer of thermal energy from one place to another through the __ of a ___ (air) or a liquid (water). This happens when molecules __ and __ leaving a blank (space), which is eventually filled by ___ that eventually __ and ___. Think of the ___ we made in class. Example: popping popcorn in a hot air popper, swimming in a lake and feeling cool, currents near your feet, or a hot air balloon rising into the air. conductor, easily allows, faster, better, conductor - ANSWER-A __ is a material that __ heat energy to flow through it. The __ the heat is able to travel through the substance the __ the __ is. There are good conductors and poor conductors, metals such as silver, gold, copper, aluminum, and stone are good conductors. insulator, NOT allow, slower, trap, - ANSWER-An __ is a material that does ___ heat energy to easily flow through it. Heat energy travels through a__ speed through these substances. Wood, paper and plastic are good insulators. They __ heat energy better than conductors. radiation, waves, through matter and space, microwave, waves, waves, sun, radiation, sun, space, Earth - ANSWER-__ is the transfer of thermal energy by ___ that move __ and ___ using a ___ produces heat energy with the assistance of a magnet to scatter the energy in the form of ___ Thermal energy is carried in ___ from the ___.
