How does thermal energy always move?
1.) From the botton of an object to it's top.
2.) From a higher temperature to a lower one.
3.) From a lower temperature to a higher one.
4.) From the surface of an object toward the inside.
2.) From a higher temperature to a lower one.
Which of the following is transfer of heat due to the movement of fluid or gas?
1.) Condensation.
2.) Convection.
3.) Combustion.
4.) Conduction.
2.) Convection.
Which of the following is an example of radiation?
1.) Chloe’s toes are cold, so she props them up on the warm radiator.
2.) Mason has to bake a cake in the summertime, so the kitchen becomes unbearably hot.
3.) The soup in the pot on the stove comes to a boil, so Elle turns down the heat.
4.) The ladle has been sitting in the pot of hot soup for a while, so Logan uses a potholder to pick the ladle up.
4.) The ladle has been sitting in the pot of hot soup for a while, so Logan uses a potholder to pick the ladle up.
wrong
Apologies for the incorrect response. The correct answer for an example of radiation is:
1.) Chloe’s toes are cold, so she props them up on the warm radiator.
Radiation refers to the transfer of heat through electromagnetic waves, such as infrared radiation in this example.
Which of the following is an example of conduction?
1.) Madison is shivering, so she stands in a sunbeam to warm up.
2.) Abby has cold hands, so she wraps her fingers around a cup of hot cocoa.
3.) The charcoal grill is finally hot enough, so Michael starts cooking the steaks.
4.) The ice cream that was left out is melting on the counter, so Edward puts it back in the freezer.
2.) Abby has cold hands, so she wraps her fingers around a cup of hot cocoa.
Conduction refers to the transfer of heat through direct contact between objects. In this example, heat is being transferred from the hot cocoa to Abby's hands through conduction.
