Electrical energy is used to turn the blades of a fan. The amount of energy transformed is seen here: 750 J electrical energy is
transformed into 400 J kinetic or mechanical energy. What happened to the remaining 350 J of energy? A) It was lost due to friction. B) It was transformed into 350 J of heat energy. C) It was destroyed by the rotating blades of the fan. D) It was never used and therefore was not transformed.
The remaining 350J of energy must have been transformed into 350J of heat energy.
A fan works by converting electrical energy into heat energy.
According to the third law of thermodynamics "no system is 100% efficient". The conversion of the energy from one form to another involves a lost in energy.
Heat is one very familiar way by which energy can be lost.
Some component energy is used to heat the fan in the process and it is a wasted energy.
mass number remains constant while atomic number has been increased by 1 unit . beta is electron like element where its mass number is 0 and atomic number is -1.
A mixture is a compound of two or more substances a pure substance is only made of one kind of atom and a solution is composed of a liquid substance made of two or more types of atoms
