The temperature of a 75 g sample of material increases from 15 oC to 45 oC when it absorbs 2000 J of energy as heat. What is the specific heat of the material?

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
