Question

what is the best definition of radiation? the average kinetic energy of all the particles in an object the heat required to raise the temperature of one gram of a substance one degree celsius. the transfer of energy by electromagnetic waves. (you can feel this from a bonfire or heat lamp.) heat is transferred by the movement of currents within a fluid (a liquid or a gas)

Explanation:

• The average kinetic energy of all the particles in an object is the definition of temperature, not radiation.
• The heat required to raise the temperature of one gram of a substance one degree Celsius is the definition of specific heat capacity.
• Heat transferred by the movement of currents within a fluid (a liquid or a gas) is the definition of convection.
• Radiation is the transfer of energy by electromagnetic waves. Examples include feeling heat from a bonfire or heat lamp.

Answer:

The transfer of energy by electromagnetic waves. (You can feel this from a bonfire or heat lamp.)
