← A silver spoon and a cup of salt water are both warmed from 20 °C to 40 °C. How does each conduct electricity afterwards?The electrodes of a home-made cell are rectangles of 4.0 cm by 2.5 cm, facing each other 2.5 cm apart. Salt water between them gives a resistance of 31 Ω. What is the conductivity of the salt water? →
