What makes a substance a good insulator

Chemistry

Answer:

zoo wee mama

Explanation:

The particles that make up an object are held together by bonds. Insulators have strong bonds that hold their particles rigidly in place. This prevents particles from gaining energy and increasing the temperature. Wool, dry air, plastics, and polystyrene foam are all examples of good insulators.

I believe the answer is A. <span>make a softer sound because the shark will not hear the softer signal.
</span><span>
I say this becasue "</span><span>Some of the sounds dolphins make are outside the range of human hearing." So that means the the dolphins speak at a higher wavelength then us humans and we can't hear it so they could use that to their advantage and speak at a height wavelength to each other when sharks are near. 

I could be wrong, but I think the answer is A. </span>

1. A high surface tension and a high boiling point both indicate that there
enyata [817]

The liquid that is expected to have the weakest intermolecular interaction is the liquid that has the lowest boiling point and surface tension.

<h3>What is boiling point?</h3>

The term boiling point refers to the temperature at which the atmospheric pressure and the pressure of the liquid becomes equal. The greater the intermolecular forces of attraction between molecules the higher the boiling point of the solid. Also a high surface tension indicates a strong  intermolecular forces of attraction between molecules.

The liquid that is expected to have the weakest intermolecular interaction is the liquid that has the lowest boiling point and surface tension.
