Answer:
mass and distance
Explanation:
The strength of this force depends on the <u>mass</u>
of each object and
the <u>distance</u>
between them.
Answer:
Ionic compounds: They have high melting points and boiling points. That is, ionic compounds are non-volatile.
Covalent compounds: They have usually low melting points and boiling points. That is, covalent compounds are usually volatile.
This type of heat transfer is radiation since we can experience the heat from an object without being in contact with it. Energy is being emitted by electromagnetic waves or in moving subatomic particles. Radiation is a consequence of thermal agitation of the molecules.
OK so basically you want to control the experiment because you want to make sure that the data to be valid.
