By radiation.
Not quite. Heat is a result of combustion, but fire is actually chemical energy.
chemical potential energy (in the fuel being burned) to heat (thermal) energy and a little light energy.
Fire's heat is a form of thermal energy, which is the energy that comes from the movement of particles within matter.
The energy transfer from the fire to the person's hands is primarily thermal energy. Heat is being transferred through conduction from the warmer fire to the cooler hands, providing warmth to the hands.
Heat is thermal energy.
Heat and radiant energy
Mechanical energy is being converted to thermal energy as the scout rubs the sticks together, creating friction that generates heat to ignite the fire.
Chemical and heat energy.* * A campfire converts chemical energy to heat energy.
The fire is not created from nothing but rather a result of the energy stored in the matchstick being converted into heat and light through friction and ignition. Energy is simply being transformed from one form to another in this process, following the law of conservation of energy.
Conservation of heat
It is a natural source of heat energy
The "Q" symbol represents heat release rate in fire dynamics, which is the amount of heat being released per unit of time during a fire. It is a key parameter used to understand and quantify the energy being generated by a fire, which influences fire behavior, spread, and potential hazards.
