From the following heats of reaction: 2 H2 (g) + O2 (g) --> 2 H2O (g) ∆H = - 483.6 kJ 3 O2 (g) --> 2 O3 (g) ∆H = +284.6 kJ Calculate the heat of the reaction for: 3 H2 (g) + O3 (g) --> 3 H2O (g)

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.
