In an electrolytic cell, electrical energy drives a chemical decomposition reaction. In a voltaic cell, a decomposition reaction generates heat energy.
chemical reactions are driven by heat energy.
spontaneous redox reactions generate electrical energy.
nonspontaneous redox reactions generate electrical energy.

elements make up everything, and they combine to make compounds.

the answer is c

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.
