Passing electric current through a heater rod is primarily a physical change. The process involves the conversion of electrical energy into thermal energy, which heats the rod without altering its chemical composition. While this heating can lead to physical changes, such as expansion, the material itself remains unchanged at the molecular level. Therefore, no new substances are formed, indicating a physical rather than a chemical change.

Is passing electric current a physical or chemical?
Passing electric current through a substance typically results in a physical change rather than a chemical change. In conductors, the current can cause the movement of charged particles without altering the chemical composition of the material. However, in electrolytic processes, such as electrolysis, the current can lead to chemical reactions, resulting in the formation of new substances. Thus, whether it is physical or chemical depends on the context and the materials involved.
What is the process of initiating a chemical reaction by passing an electric current through an electrolytic solution?
This process is the thermal decomposition.
Passing a magnetic field by a wire creates a what?
Passing a wire near a magnetic field induces an electric current in the wire.
What causes Electric shock injuries?
Electric shock injuries are caused by lightning or electric current from a mechanical source passing through the body
What is called the unit of electric current?
The unit of electric current is called the ampere, which is symbolized as "A". It represents the rate of flow of electric charge or the amount of charge passing through a point in a circuit per unit time.
Who discover chemical effect of electric current?
The chemical effect of electric current, known as electrolysis, was discovered by William Nicholson and Anthony Carlisle in 1800. They found that passing an electric current through water caused it to split into its constituent elements, hydrogen and oxygen.
Is decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.
What is the process of breaking down something using an electric current?
Electrolysis is the process of using an electric current to break down a chemical compound into simpler substances. It involves passing an electric current through a conducting solution or molten compound, causing the compound to decompose into its constituent elements or ions.
What are electromagents?
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
Which type of chemical reaction takes place when electric current is passed through water?
The process is called electrolysis, and it usually results in a decomposition reaction. For example, passing an electric current through water results in the reaction 2H2O --> 2H2 + O2.
What is the process of initiating a chemical reaction by passing an electric current through an electrolytic solution?
This process is the thermal decomposition.
What molecules make h2o?
mainly, an electric current passing throught
Clearly state the definition of electrolysis?
Electrolysis is a chemical process where an electrolyte is chemically decomposed into its consituents by passing an direct electric current through it inside an electric cell.
Enlist any four effects of electric current on conductor with one example of each?
Effects of an Electric current -1) Heating effect -e.g. - Heater / Geyser etc.2) Magnetic effect -e.g. - Electric Bell etc.3) Chemical effect -e.g. - Battery charging etc.4) Lighting effect -e.g. - Electric bulb etc.
What makes H2O molecules separate?
mainly, an electric current passing throught
Electric current is measured using what device?
ammeter, which is understood as an amp meter
What is Decomposition of a material by an outside electric current call?
The process of decomposing a material by an outside electric current is called electrolysis. It involves passing an electric current through a substance to break it down into its component parts.
