True or False: The resistance of a conductor is affected by its temperature.

The resistance of a conductor is indeed affected by its temperature, making the statement true. When the temperature of a conductor increases, the kinetic energy of its atoms rises, leading to more frequent collisions between the electrons (which carry current) and the atoms of the conductor. This results in an increase in resistance.

For most metallic conductors, resistance tends to increase with temperature due to this increased scattering of electrons. This relationship is a fundamental principle in the study of electrical conductivity and is described quantitatively by the temperature coefficient of resistance, which characterizes how the resistance of a specific material changes with temperature.

In contrast, some materials, like semiconductors, may behave differently; as temperature rises, their resistance can decrease due to the increased availability of charge carriers. However, in the context of this question, which addresses the general relationship of resistance in conductors, the correct answer is that resistance does indeed increase with temperature.
