endothermic
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
Nuclear fusion. But it really doesn't "create" energy - one type of energy is converted to another type.
some type of exploding gas!
Exothermic
Technically, no process "creates" energy. Energy cannot be created, or destroyed for that matter. The total amount of energy in the Universe remains constant. It is possible to convert one type of energy to another, though.
endothermic because the energy is absorbed
endothermic, because energy is absorbed from the surroundings
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
Endothermic, because energy is absorbed from the surrounding (Apex Physics 2023)
Exo -> Greek "Outside" Therm -> thérmē -> Greek "Heat" So an exothermic reaction releases heat energy. Related to that type of reaction is the endothermic reaction in which heat is absorbed into the reaction rather than being released by it.
Endothermic. Assuming the energy absorbed is heat. Exothermic reactions release heat, such as the oxidation of hydrogen to create water.
Fluorescence is light energy produced by a process where high-energy radiation (such as ultraviolet or X-ray) is absorbed by electrons surrounding an atom and is re-emitted as light energy.Phosphoresence is light energy produced by a particular type of chemical reaction where the excess chemical energy of the reactants is given off as light energy.
That depends on the type of energy being absorbed or released or exchanged.
When new bonds are formed between atoms, energy is released and this process is known as exothermic process. Similarly when old bonds break, energy from the surrounding is absorbed and is known as endothermic process.
The type of reaction that absorbs energy is endothermic. This process takes the energy from its surroundings, absorbs it, and creates heat.
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
Exothermic reactions. Such as combustion or reactions whereby the energy required for bond forming is greater than the energy absorbed for bond breaking.
