Internal energy is defined as the energy associated with the random, disordered motion of molecules.................
External Energy is defined as the energy associated with placing the atoms in the control volume (flow work), at the boundary (boundary work) or across the system boundary (shaft work)
Cards with a source?
processes which bring about changes on the surface of the earth are called external processes.
the process in the green plants in certain other organisms by which carbohydrates are synthesised from carbondioxide and water using light as an energy source

External Injuries- Injuries that happen on the outside of your body/on your skin, eg Cuts, Bruises.
The sun is the major external source of energy.
solar energy
Solar energy :)
The sun because it gets its enegry from it to make food
The Sun is Earth's primary external energy source. Solar radiation emitted by the Sun provides heat and light energy to sustain life on Earth through a process called photosynthesis.
Glucose is the external fuel of choice used by cells as a ready source of energy. Cells break down glucose through a series of metabolic pathways to produce ATP, the primary energy currency of the cell.
connected to an energy source or containing residual or stored energy
connected to an energy source or containing residual or stored energy
Energy is added in the illustration through the input of some external source, such as a battery or a power supply. This external source provides the necessary energy to the system, allowing it to perform its intended function.
The term clean source of energy refers to only primary energy sources as wind or solar energy. Electricity, by definition, is not a primary energy source. It is a secondary energy source that is could be produced by a clean energy source as wind or any renewable primary energy source or produced by fossil energy source as oil, natural gas, or coal.
Exothermic reaction
Nuclear energy requires an external source of energy to initiate the nuclear fission or fusion reactions that produce energy. This initial energy input is typically in the form of electricity or another type of fuel to start the chain reaction.
