Which particles have the smallest amount of energy
-
Solid
-
Liquid
-
Gas
Correct Answer
A. SolidExplanation
Solid particles have the smallest amount of energy compared to liquid and gas particles. In a solid, the particles are closely packed together and have the least amount of movement. They vibrate in fixed positions, resulting in lower energy levels. In contrast, liquid particles have more energy as they are more loosely packed and can move around each other. Gas particles have the highest energy levels as they are the most spread out and can move freely in all directions. Therefore, solid particles have the smallest amount of energy.Rate this question:

Why can't we compress solids and liquids?
-
The particles are too far apart
-
The particles have too much energy
-
The particles are too close together
Correct Answer
A. The particles are too close togetherExplanation
Solids and liquids cannot be compressed because the particles are already tightly packed and close together. In solids, the particles are arranged in a fixed pattern and have very little space to move. In liquids, although the particles are not arranged in a fixed pattern, they are still closely packed and have minimal space between them. Therefore, any attempt to compress solids or liquids would require the particles to be pushed even closer together, which is not possible due to their already close proximity.Rate this question:

Diffusion is when....
-
Particles move from where there a lot to where there are fewer.
-
Particles move from where are a few to where there are more.
-
Solids turn into liquids
Correct Answer
A. Particles move from where there a lot to where there are fewer.Explanation
Diffusion is the process by which particles move from an area of high concentration to an area of low concentration. This movement occurs until the concentration of particles is equalized or balanced. Therefore, the correct answer is "Particles move from where there are a lot to where there are fewer."Rate this question:

When a solid turns into a liquid, it is called...
-
Boiling
-
Evaporating
-
Melting
Correct Answer
A. MeltingExplanation
Melting refers to the process in which a solid substance changes into a liquid state. This occurs when the temperature of the solid is raised to its melting point, causing the particles to gain enough energy to overcome the forces holding them together in a solid structure. As a result, the solid's rigid arrangement breaks down, and it transforms into a more fluid and less organized liquid state.Rate this question:

The crystals that made the water go purple were...
-
Sodium chloride
-
Potassium permanganate
-
Potassium chloride
Correct Answer
A. Potassium permanganateExplanation
Potassium permanganate is a strong oxidizing agent that can react with various substances, including organic matter and certain chemicals, causing a change in color. In this case, when potassium permanganate crystals are added to water, they dissolve and release manganese ions, which react with water molecules to form a purple-colored compound. Therefore, the presence of potassium permanganate crystals is responsible for turning the water purple. Sodium chloride and potassium chloride do not have the same oxidizing properties and would not cause a color change in water.Rate this question:

Why do you think sound travels faster in water than in air? (Hint: think about the particles in water and those in air)
-
The particles are further apart in water than in air
-
Liquids can flow so sound flows too.
-
The particles are closer together in water than in air.
Correct Answer
A. The particles are closer together in water than in air.Explanation
Sound travels faster in water than in air because the particles in water are closer together compared to the particles in air. In a denser medium like water, sound waves can propagate more quickly as the particles can transmit the vibrations more efficiently. This is why sound travels faster in water.Rate this question:
