The force of gravity depends on what 2 things

The masses of the objects and the distance between them

Explanation:

The formula for the force (F) of gravity is  

where m₁ and m₂ are the masses of the two objects and r is the distance between them.

Thus, the force of gravity depends on the

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

your answer is rna to the question.
