radiation
The fireplace's heat is an example of radiation.
C. Radiation
convection to heat the room conduction to heat the metal work and brick work
Heat given off by a fire in a fireplace is an example of thermal energy transfer through radiation when the hot objects emit infrared radiation that is absorbed by cooler objects in the room, warming them up.
C. Radiation I just took the test
It is Heat that is 'given off' by a chemical reaction.
When energy is lost in an environment, it is typically given off as heat. This heat can contribute to increasing the overall temperature of the environment.
"C", radiation.
The friction creates the heat.
