In a temperature-resistivity graph, what does the slope represent for a metallic conductor?
Step 1: Understand that a temperature-resistivity graph shows how the resistivity of a metallic conductor changes with temperature.
Step 2: Recognize that resistivity is a property that indicates how strongly a material opposes the flow of electric current.
Step 3: Identify that the slope of the graph is the steepness of the line that connects points on the graph.
Step 4: Know that the slope indicates how much the resistivity changes for each degree change in temperature.
Step 5: Conclude that this change is quantified as the temperature coefficient of resistivity, which tells us how sensitive the resistivity is to temperature changes.
