Question

1. in a solution the being dissolved. a. solute b. solvent water is the solvent. 8. what is the difference between dissolving and melting? label the diagram below. phase change diagram 9. kinetic energy 10. particles 11. heat is 6. kinetic energy 7. particles 8. heat is word bank melting freezing condensation evaporation decreases speed up slow down increases added taken away

Explanation:

Step1: Define solute and solvent

In a solution, the substance being dissolved is the solute, and the substance doing the dissolving is the solvent. So for question 7, the answer is a. solute.

Step2: Differentiate dissolving and melting

Dissolving is a process where a solute mixes with a solvent at the molecular - level. Melting is a phase change of a solid to a liquid due to an increase in temperature. They are different physical processes.

Step3: Analyze phase - change diagram

• As heat energy is added (moving right on the x - axis), kinetic energy of particles increases. So for 6 and 9, the answer is "increases".
• As heat energy is added, particles speed up. So for 7 and 10, the answer is "Speed up".
• When going from solid to liquid (melting) and liquid to gas (evaporation), heat is added. So for 8 and 11, the answer is "added".

Answer:

1. a. solute
2. Dissolving is a mixing process at the molecular level between a solute and a solvent, while melting is a phase - change of a solid to a liquid due to temperature increase.
3. increases
4. Speed up
5. added
