b. 0 K
1. 4.1. In Wikipedia, look up "Kelvin" and an-
swer this question: The Kelvin scale is a
temperature scale like the Celsius temper-
ature scale (1 deg C = 1 deg K), but they
are shifted from each other. Kelvin is the
predominantly used for scientific purpos-
es. What is the lowest theoretical temper-
ature that can exist in the universe on the
Kelvin scale?
a. Heat from the original formation of plan-
2. 4.2. In Wikipedia, look up "Earth's internal
et.
heat budget", scroll down to "Primordial
heat", and answer this question: What is
primordial heat?
c. 50%
3. 4.3. In Wikipedia, look up "Earth's internal
heat budget", scroll down to "Radiogenic
heat", and answer this question: What per-
cent of the Earth's internal heat originates
from radioactive decay?
b. An elliptical orbit
4. 4.4. In Wikipedia, look up "Tidal heating"
and answer this question: Tidal heating
occurs when gravitational forces cause a
body like a moon to deform, which creates
heat. This happens whenever something is
deformed due to internal friction. However,
for heat to be sustained, the moon must
continually deform, like an accordion being
played. What kind of orbit is required in
order to induce sustained tidal heating?
