The temperature of a substance is a measure of the average
select one:
a. attractive forces between its molecules
b. mass of its molecules
c. potential energy of its molecules
d. kinetic energy of its molecules

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

the dissolution of polymer can be thermodynamically described in 2 steps.
