Which of the following reactions shows a chemical change producing a solid? A. H2(g) + O2(g) → H20(1)
B. 2CH3OH(1) + 302(g) → 2C02(g) + 4H2O(1)
C. NaCl(s) → NaCl(aq)
D. 2AgNO3(aq) + CaBr2(aq) + 2AgBr(s) +
s) + Ca(NO3)2(aq)

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.
