Intermolecular forces are forces that keep molecules together. For example, the forces between two water molecules. The stronger the intermolecular forces are, the more "solid" is the matter going to be, meaning that the intermolecular forces are the strongest in solids and weakest in gases.
Make sure not to confuse intERmolecular forces (forces between *molecules*) and intRAmolecular forces (forces between *atoms* that make up a molecule).
I think this is the answer:
<span>Matter can change its state because of the pressure and/or the temperature.</span>
<span>The lighter object is in orbit around the heaviest, and the Sun is the heaviest object in the Solar System</span>
Acceleration in m/s^2 = 2/10 = 0.2 m/s^2
Answer: to only change one factor in an experiment or test
