4. The combustion of propane (C3H8) with O2 according to the given balanced chemical equation releases 531 kcal. How many kilocalories of energy are released when 0.750 mol of propane is burned?

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.

: )

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
