Temprature increase the resistivity of a metal as electrons has to travel further against the thermal temprature as increase in temprature will increase the diffussion of electrons while in semi conductor this is dependent on the electric field intensity and charge carrier either n type or p type.
Not sure, in my 9th standard (level of Indian standard education),we studied about conductors....."when temperature increases conductivity of a conductor is also increases". but it is not true in all case because of the properties of the conductors. in some case ...'temperature increase the resistance of a conductor increases so conductivity decreases '. for example: in olden days electronic equipments is more efficient when the atmospheric temperature increases or presence of heat .
Increasing the temperature of a conductor will typically increase its electrical resistance, reducing its conductivity. This is due to increased collisions between electrons and atoms in the conductor, hindering electron flow. Extremely high temperatures can cause a conductor to ultimately melt or break down.
To make a poor conductor into a better conductor, you can increase its conductivity by adding impurities or doping materials, applying heat to increase kinetic energy of charge carriers, or reducing its length to decrease resistance. In general, manipulating factors that affect conductivity such as temperature, impurities, and length can improve a material's ability to conduct electricity.
The conductivity depends on the passage of charged particles especially electrons. In metals electrons are easily available in conduction band and so its conductivity is high. As we increase the temperature then core of atoms vibrate largely. So with positive charge it could easily minimize the electrons in the conduction band and hence fall in conductivity In case of semiconductor there will be usually forbidden gap between valence band and conduction band. So conduction is poor at ordinary temperature. But as we increase temperature that would allow electrons to reach conduction band as covalent bonds get broken. Hence higher conductivity
You can increase the conductivity of a semiconductor by doping it with impurities to increase the number of charge carriers (electrons or holes). This can be done by adding elements that provide extra electrons (N-type doping) or by adding elements that create holes (P-type doping). Additionally, raising the temperature can also increase the mobility of the charge carriers, thereby increasing conductivity.
The conductivity of a semi-conductor can be increased by raising the temperature of the semi-conductor .

yes temperature affects the conductivity of conductor and semi conductors but in case of insulators temp. has no effect. While we talk about conductors as temp. increases conductivity decreases ,the question is why, look if we take an example of copper the conductivity is so high at normal temperature because the molecules in the copper are so close but when we increase temperature the inter molecule distance increases and result is increasing resistance of the copper, and as we know that resistance is inversely proportional to the conductivity. So in the case of conductor, temperature affects the conductivity. Hey may be you are familiarize with the new aspect called superconductivity, the same effect is here while the temperature of a conductor is so low approximately -273degree the conductor becomes superconductor because Resistance become so low (can say approx. 0 but not exact 0). You should know that most metals increase their electrical resistivity by about 0.005 per degree. Good luck Rjames007
Solid sodium chloride is neutral.
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
conductivity of semiconductors increases with increase in temperature as breakdown of covalent bonds take place in the semiconductor due to increase in temp but more & more increase in the temp may result in the breakdown or damage of the semiconductor which results in the decrease in conductivity of semiconductor
Molar conductivity is what increases dilution. It is the conductivity of an electrolyte solution.
The element that increases its electrical conductivity as its temperature increases is typically a metal, such as copper or silver. This behavior is due to more free electrons being available to carry electric current at higher temperatures, leading to an increase in conductivity.
With the increase in temperature if the resistance increases or the current in the circuit decreases then it is said to be have positive temperature coefficient .But in semi-conductors with the increase in temperature the electrons present in the valance band are excited and they would enter the conduction band for conduction . As the no. of charge carriers always increase in a semi-conductor , implies that the current always increases with the increase in temperature so the semi-conductor can never have positive temperature coefficient
