59. Conduction is A) the direct transmission iof energy without the need for a medium of transfer. B) the transfer of heat via bulk motion of the medium. C) the transfer of heat by electron and atomic collisions. D) the only way to transfer heat from a colder object to a warmer ones. 60. Convection is A) the direct transmission of energy without the need for a medium of transfer. B) the transfer of heat via bulk motion of the medium. C) the transfer of heat by electron and atomic collisions. D) the only way to transfer heat from a colder object to a warmer ones. 58. When you touch the metal handle of the room -temperature stainless-steel frying pan, it feels cool to your touch. When you grab a room-temperature sauce pan by its plastic handle, A) it feels cooler than the metal handle because plastic conducts heat better than the metallic steel. B) it feels warmer than the metal handle because the steel handle conducts heat better than the plastic. C) it doesn't feel cooler or warmer than the steel. Why would it? Both handles are at room temperature! 2 points 2 points 2 points

Answer

59. C) the transfer of heat by electron and atomic collisions. ### 60. B) the transfer of heat via bulk motion of the medium. ### 58. B) it feels warmer than the metal handle because the steel handle conducts heat better than the plastic. Explanation 1. Identify conduction Conduction is the transfer of heat by electron and atomic collisions. Therefore, the correct answer for conduction is C. 2. Identify convection Convection is the transfer of heat via bulk motion of the medium. Therefore, the correct answer for convection is B. 3. Analyze temperature perception The metal handle feels cooler because it conducts heat better than plastic, drawing heat away from your hand more efficiently. Therefore, the correct answer is B.
