How does the gas electrical conductivity vary with different factors?
The electrical conductivity of gas can vary based on factors such as temperature, pressure, and the presence of impurities. Generally, higher temperatures and pressures can increase conductivity, while impurities can either increase or decrease conductivity depending on their nature.
When the temperature increases thermistor resistance decreases?
Yes, that's correct. In a thermistor, which is a type of temperature-sensitive resistor, the resistance decreases as the temperature increases. This is because the conductivity of the thermistor material increases with temperature, causing the resistance to decrease.
What is the relationship between temperature and air conductivity?
The relationship between temperature and air conductivity is that as temperature increases, air conductivity also increases. This means that higher temperatures can lead to better conductivity of electricity through the air.
Why does the electrical conductivity of pure metal decrease with temperature while that of semiconductors increases?
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
How does thermal conductivity change with temperature?
Thermal conductivity generally increases with temperature. This means that as temperature rises, materials are better able to conduct heat.

What is the factors that affecting conductivity of copper?
Factors affecting the conductivity of copper include temperature (higher temperatures decrease conductivity), impurities in the copper (impurities reduce conductivity), and the crystalline structure of the copper (grain boundaries can impede electron movement). Additionally, the length and cross-sectional area of the copper wire can also affect its conductivity.

Yes, that's correct. In a thermistor, which is a type of temperature-sensitive resistor, the resistance decreases as the temperature increases. This is because the conductivity of the thermistor material increases with temperature, causing the resistance to decrease.
How does temperature affect the physical properties of petrol?
An increase in temperature will reduce the density, reduce the viscosity, reduce thermal conductivity, and increase the specific heat capacity. A decrease in temperature will have the opposite affect.

How do you decrease conductivity in WFI?
To decrease conductivity in Water for Injection (WFI), you can use techniques like reverse osmosis or deionization to remove ions from the water. These processes can help in reducing the conductivity by eliminating dissolved solids that contribute to conductivity. Regular monitoring and maintenance of the water system also help in maintaining low conductivity levels in WFI.
How does thermal conductivity change with temperature?
Thermal conductivity generally increases with temperature. This means that as temperature rises, materials are better able to conduct heat.
If an iron rod is heated to a high temperature how would it effect its conductivity?
Generally speaking conductivity of metals decreases as the temperature increases.
What is the relationship between temperature and conductivity?
The relationship between temperature and conductivity is that conductivity generally increases as temperature increases. This is because higher temperatures cause particles in a substance to move more quickly, which allows for better flow of electric current.
What is the temperature of a soda if you put it in ice for 30 mins?
The temperature of the soda will decrease due to the ice's lower temperature, but it will not reach the same temperature as the ice. The rate of cooling will depend on various factors such as the initial temperature of the soda, the amount of ice, and the thermal conductivity of the container.
What is the effect of temperature on transistor?
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
