B. Speed up chemical reactions
A lot of heat like a lot no cap it’s gonna he a lot
Answer:
Covalent
Step-by-step explanation:
Covalent substances have relatively weak intermolecular forces. Many covalent substances such as hydrogen and oxygen are gases at room temperature, so they have low melting points.
<em>Ionic substances</em> have strong ion-ion attractive forces, and <em>metals </em>have strong metallic (electron-metal cation) attractions. I don't know of any metals or ionic compounds that are gases at normal conditions.
Answer:
D
Explanation:
Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly.
