Answer:

C. Heat must be added or removed

Explanation:

When matter changes states it is due to the overall loss or gain of heat. In addition, heat being added or removed is what will cause a temperature change, but a simple temperature change is not enough to change states. For example, a temperature could go from 50 degrees to 51. This will not cause a change in states. So heat must be added or removed in order for matter to change states.

________ are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds

olga_2 [115]

<u>Hydrogen bonds </u>are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.

The hydrogen bond is weak bond.

The hydrogen bond is electrostatic force of attraction between hydrogen atom and more electronegative atoms or group ( like Florine , oxygen or nitrogen) which is contently bonded.
The hydrogen bond is occur in polar , contently bond atoms in different molecules.
Example is H-O-H or $NH_{3}$
The positively charged hydrogen side of one water molecule is bond with negatively charged oxygen side of another molecule.
