Question

Quizplus · Accepted Answer

Density, viscosity, and electrical resistance all vary with temperature. Density decreases with increasing temperature due to thermal expansion, viscosity also decreases with increasing temperature, and electrical resistance generally increases with increasing temperature due to increased atomic vibrations and collisions.
