Question

PLEASE PLEASE PLEASE HELP AND GIVE EXPLANATION TOO!

FOR EXAMPLE: THE TYPE OF HEAT TRANSFER IS RADIATION BECAUSE...

*I ALREADY WROTE THE TYPE OF TRANSFER DOWN I JUST NEED EXPLANATIONS*


1.) Candle - The type of heat transfer here is radiation because...


2.) Tea Kettle & Mugs - The type of heat transfer here is conduction/convection because...


3.) Lamp - The type of heat transfer here is radiation because...



7.) Toaster - The type of heat transfer here is conduction/convection/radiation because...


9.) Radiator/Heater - The type of heat transfer here is radiation because...

Answer 1

Step-by-step explanation:

1. a burning candle enits radiation in the form of heat and light, this is because of it emission of energy in rays or waves

2.tea and kettle mugs transfer heat by the actual movement of matter. heat leaves the nug as the currents of the steam and air rise. This also emmits heat to the surrounding area.

3.Radiation refers to the emission of energy in rays or waves. In this, a lamps energy is emmiting rays of heat the expands its heat and light to the surrounding area.

7. the coils in the toaster heat the air which heats the toast. A toaster uses infrared radiation because when you put food in the coild glow red.

9. this is beacuse, low wavelength, non visable infared radiation can carry heat directly from warm objects to cooler objects. It emmits and expands its heat energy to the surrounding area and other objects.
