100 kj of energy is introduced to your cell phone while it charges but 10 kj of energy is lost in the process as heat given off to the surroundings. what is e for the system?

Sagot :

The energy of the system is 90 kJ.

Energy is a quantitative property given to a body or physical system and can be identified as work being done in the form of heat and light.

Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed. Energy is the ability to do work. It can exist in electrical, kinetic, thermal, electrical, chemical, nuclear, or other forms.

calculation:-

energy introduced = 100kj

energy lost in the surrounding = 10 kJ

total energy = system + surrounding

100k = system + 10kj

system = 100 - 10 kj

= 90kJ

Energy exists in many forms. Examples include light energy, thermal energy, mechanical energy, gravitational energy, electrical energy, acoustic energy, chemical energy, and nuclear or atomic energy. Each form can be transformed or changed into other forms.
