They don't "possess" any energy, in the sense that they don't have any significant amount of energy stored. They need to be plugged in to work. When they do, they use electrical energy.
The major forms of energy include kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), radiant energy (light), chemical energy (stored in bonds between atoms), and electrical energy (flow of electrons).
heat energy
Because carbon posess tetravalency
Matter, by definition, must posess both mass and volume. Energy is in the form of waves, which posess neither mass nor volume.
Starting energy form: Chemical energy End energy: Electrical energy--> heat,sound,light energy
No, since the person inside the lift is usually fixed to one spot and stationary objects do not posess kinetic energy.
posess
No, the energy that powers a computer is electrical energy. Chemical energy is energy that is stored in the bonds of molecules. Batteries, candles, matches and food are some things that have chemical energy. When the molecules/compounds' bonds are broken, the chemical energy is released. In a candle, this would cause a small fire. Electrical energy is the movement of electrons. The electrons move quickly inside the wire, & power the computer as electricity.
A computer uses electrical energy
The energy stored in a computer is typically in the form of electrical energy, stored in the battery or power supply unit. The amount of energy stored depends on the capacity of the battery or power supply, which can vary based on the device and its specifications.
YES
the term "lost" means that it's completely disappear, if so, no. It still turn into another type of energy (which i don't know) due to newton law no.2, an object can posess energy through height.
