select one:
a. the center of the milky way
b. a space ship in orbit about earth
c. the sun
d. earth

I think letter b? Dont count on it :) like is the question asking what can be an equivalent to the motion of our planets?

Explanation:

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
