Energy is only transformed from one form to another. In exothermic reaction the energy within the bonds is transformed into energy released as heat
You don't. A light bulb transforms only a fraction of its energy into light, and most of it into heat. For an incandescent bulb about 3% is transformed into light, while for a compact fluorescent (low-energy light) about 15% is transformed into light.
Energy cannot be created nor be destroyed.It can only be transformed from one form to another.eg of conversion from light energy to heat energy is the sunlight which is converrted to heat energy.
It appears as heat
The rest is dissipated as heat.
energy is not created or destroyed. only transformed.
energy is not created or destroyed. only transformed.
no it can only be transeferred into electrical or chemical energy
We know that that process is what goes on inside stars and generates the energy they radiate into space, and we cause the same process to occur and to generate energy in nuclear power plants and weapons.
energy cannot be produced or destroyed, only transformed.
Wind is the only one.
Friction causes heat. Fraction causes heat only with people who are not comfortable with maths.
