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 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 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 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.
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
Is the heating element on a stove a chemical reaction?
No. It is a physical process cause be passing an electric current through a wire.
Is electrical conductivity physical change or chemical?
Yes
What physical quantity corresponds to the rate of flow of charge?
The physical quantity that corresponds to the rate of flow of charge is current, which is measured in amperes (A). Current represents the flow of electric charge per unit of time through a conductor.
