Is electrical conductivity physical change or chemical?
Yes
Is poor conductor of electricity chemical or physical property?
Poor conductivity of electricity is a physical property, as it is determined by the material's ability to allow the flow of electric current. This property depends on the arrangement and behavior of the material's electrons, rather than its chemical composition.
How can an element be separated?
Elements can be separated through physical or chemical methods. Physical methods include filtration, distillation, and chromatography, which separate elements based on their physical properties. Chemical methods involve reactions that convert one element into a different chemical species, allowing them to be separated based on their chemical properties.
What effect does electric current have on chemicals?
Electric current can cause chemical reactions by transferring electrons between substances, leading to the formation of new compounds. This process is known as electrolysis. Additionally, electric current can change the pH of a solution by generating acidic or basic products at the electrodes.
What is an example of the energy transformation chemical to electric?
An example of energy transformation from chemical to electric is in a battery. In a battery, chemical energy stored in the electrodes is converted into electrical energy when the circuit is completed and electrons flow from the anode to the cathode, creating an electrical current.
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 are some methods for decomposing compounds?
thermal decomposition: decomposing by the means of heatelectric decompostion: decomposing by sending a electric current through the compoundthere are some mor e but these are all i know
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.
Is electromotive a physical or a chemical property?
Its a physical property as it is not involved with chemical reactions.
Is electrical conductivity a chemical change?
No, electrical conductivity is a physical property that depends on the ability of a material to carry an electric current. It is not a chemical change because the chemical composition of the substance remains the same.
What role does electric current play in a megnetic levitating trian?
The role electric current plays in is the physical and chemical stages. No only does the current provide the use of elctricity and the mocement of atoms but its also used as a scientific research. Its an mass linking into a atom.
What are the effects of electric current?
current has five effects. 1. physical effects 2. xray effects 3. heating effects 4. chemical effects 5.magnetic effects.
Is passing electric current through a heater rod itphysical or chemical change?
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 a filament of a light bulb glows when an electric current flows through it is a chemical change?
It is a physical change brought about by the exitation of molecules producing heat and light. A general rule of thumb is that a physical change can be repeated on an article and chemical change cannot. Remove the current from a filament and it is still a filament.
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.
When an electric current passes through water takes place breaking down the compound into hydrogen and oxygen. a physical change an atomic change a chemical change an elemental change?
When an electric current passes through water, it breaks down the compound into hydrogen and oxygen, which is known as electrolysis. This process involves the breaking of chemical bonds and the formation of new substances, indicating a chemical change. Thus, the correct answer is a chemical change.
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
