Question
Chapter 25, Problem 1ASA
To determine
Whether the resistance of all the substances increases with temperature or not.
Expert Solution & Answer
Answer to Problem 1ASA
The electric resistance of a substance changes with the change in temperature.
Explanation of Solution
With the changes in temperature of a substance, the electric resistance of the substance also changes. The change in resistance of a substance is directly proportional to the temperature change. The resistance-dependent temperature is typically expressed as coefficient of resistance.
Conclusion:
Material resistance doesn't need to increase with temperature rise. Some metals are responsive to temperature rise whereas certain materials, like carbon, show decreased resistance to temperature rises.
