Question

1. a) A typical indoor temperature is 21 degree Celsius. A typical outdoor temperature for Fairbanks, Alaska in
January is -2 degree Fahrenheit. What are these temperatures in the Kelvin scale?


b) Liquid nitrogen boils at 77 K. What is this temperature in degrees Fahrenheit?


2) In the DC resistance part of this Experiment, we use a 15 ohm resistor to protect the equipment.
What would happen if we ran the experiment without the resistor?

3) Look up and express in your own words what is the difference between a paramagnetic and diamagnetic material.

Explanation / Answer

1.

a. K = C + 273.15, K = (F - 32) * 5/9 + 273.15

indoor: K = 21 + 273.15 = 294.15 K

outdoor: K = (-2-32) * 5/9 + 273.15 = 254.26 K

b. F = (K-273.15) * 1.8 + 32 = (77-273.15) * 1.8 + 32 = -321.07 F

2. The circuit would be damaged. Resistors manage the current flow.

3. Diamagnetic atoms repel magnetic fields because they only have paired electrons while paramagnetic atoms are attracted to magnetic fields because they have unpaired electrons.
