I believe the correct answer would be that b<span>oiling points and melting points are similar because they both involve the change in a state of a material, but they are different because boiling point involves a change from a liquid to a gas and melting point involves a change from a solid to a liquid. Boiling and melting are phase changes that can happen to a substance however they differ in the process that happens.</span>
Answer:
Conduction is the transfer of thermal energy from one molecule to another within an object. Conduction also happens between two objects in direct contact if they have different temperatures. The hotter molecule vibrates because of the added heat. This vibration and movement transfer the energy to the surrounding molecules. The transfer of energy continues until all the molecules have the same temperature.
Conduction takes place in solids, liquids, and gases. However, it happens fastest in solids because the molecules in solids are closely packed.
Answer:
Here is your answer: Tin,
Explanation:
Which of the following elements probably has the most properties in common with lead (Pb)? Tin (Sn).
Decrease temperature and decrease of concentration will decrease reaction rate, because less molecules will be able to react.

Answer:
[D] Same Phylum
Explanation:
To know the least closely related We need to the know this:
- Domain
- Kingdom
- Phylum
- Class Order
- Family
- genus
- Species
Domain → Broadest ⇒ Least related.
Thus, In the answer choices we know that Phylum is the least Closely related.
