The 4 x 10^-3 ohms is at temperatures very close to absolute zero.
What is ohms?
A SI-derived unit for measuring electrical resistance in materials or electrical devices. When a one-volt potential difference is applied, a one-amp current flows through the conductor, which has a resistance of one ohm.
What is resistance ?
Resistance is the obstacle that a substance offers to the flow of electrical current. The ohm, frequently written as a word and occasionally represented by the uppercase Greek letter omega, is the commonly used unit of resistance.
Use the same slope that you hopefully calculated in part A (1/40), solve for a line equation to represent the graph, and plug in 0 for the x variable (temperature here).
y=mx+b.....R=(1/40)T+4....
R(0 Kelvin) = (1/40)*0 + 4 = 4 but because R is in milliohms, 4 x 10^-3 ohms.
Therefore, 4 x 10^-3 ohms is at temperatures very close to absolute zero.
