battery
Yes, a glow stick produces light by means of a chemical change.
That would be a chemical change because the firefly produces a bio-luminescent chemical. This chemical produces light which you see when the fire fly lights up!
exothermic
A change that produces a new substance is called a chemical reaction. The substance initially involved in a chemical reaction are called reactants or reagents.
chemical change or chemical reaction.
A cell aka battery.
A chemical cell or strings of cells called a battery.
cell
A battery works by converting chemical energy into an electrical charge. Electrolytes let ions move between the positive terminal and the negative terminal, which makes the electrical current flow.
in biology, the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm in electricity, a device that produces an electric current by converting chemical or radiant energy into electrical energy
Force the water through an electric turbine generator and that produces electricity. Having water backed up behind a dam provides the push.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
A dynamo
An electromagnet, a coil of wire round a magnetic core. An electric current in the wire produces a magnetic field round the core, which contains energy which could be used to lift a load.
A device that produces an electric current by converting chemical energy into electrical energy is called a battery. A cell has a positive terminal called the cathode and a negative terminal called the anode.
Yes, a TV set produces thermal energy by converting electrical energy with the use of resistance.
