MATH: Scientists use the Kelvin temperature scale to keep track of some of the coldest things in the universe.?
The Kelvin temperature scale begins at 0 Kelvin (K), which is
called absolute zero. At absolute zero all motion stops, so nothing can ever be
colder than 0 Kelvin. The following values compares the Celsius (˚C) and
Kelvin temperature scales.^1
(K) 0, 50, 100, 150, 200, 250
(C) -273, -223, -173, -123, -73, -23
1. The temperature of liquid nitrogen is 77 K. Use the graph to estimate what the
temperature of liquid nitrogen is in degrees Celsius. Clearly show your method
on the graph.
2. Use extrapolation to determine what the approximate temperature of 0C would
be in Kelvin. Clearly show your method on the graph.

This is a linear relationship:
C = K − 273
K = C + 273
1. 77°K = 77−273 = −196°C
2. 0°C = 0+273 = 273°K
