Jasmine adds varying amounts of ice to samples of water. Which conclusion can she draw from her experiment?(1 point) Responses As ice added decreases, the water temperature decreases. As ice added decreases, the water temperature decreases. As water temperature decreases, the water molecules’ kinetic energy increases. As water temperature decreases, the water molecules’ kinetic energy increases. As water temperature increases, the water molecules’ kinetic energy decreases. As water temperature increases, the water molecules’ kinetic energy decreases. As ice added increases, the change in water temperature increases.

Joshua fills one large container with cold water Then he fills a small container with hot water and red food coloring, and seals it with a lid. Next, he puts the small container into the large container and removes the lid of the small container. He observes the red colored water from the small container rising up to the top of the cold water. Which two statements explain why this happens?(1 point) Responses because the hot water is more dense than the cold water because the hot water is more dense than the cold water because the hot water has the same density as the cold water because the hot water has the same density as the cold water because the hot water molecules move faster than those of cold water because the hot water molecules move faster than those of cold water because the hot water molecules move as fast as those of cold water because the hot water molecules move as fast as those of cold water because the hot water is less dense than the cold water
Answer
When hot water is added to cold water. In which direction does the heat energy move(1 point) Responses The heat energy moves from the hot water into the cold water. The heat energy moves from the hot water into the cold water. The heat energy moves from the cold water into the hot water. The heat energy moves from the cold water into the hot water. Equivalent amounts of heat energy move in both directions. Equivalent amounts of heat energy move in both directions. No heat energy moves, as it all remains in the hot water. No heat energy moves, as it all remains in the hot water.

To rank the potential energy of gas, liquid, and solid states from lowest to highest:
**Correct order: Solid < Liquid < Gas**
So, the appropriate choice from your options is **solid liquid gas**.
In this ranking:
- Solids have the lowest potential energy because the particles are tightly packed and have fixed positions.
- Liquids have more potential energy than solids as the particles are still close together but can move around more freely.
- Gases have the highest potential energy as the particles are far apart and move freely, allowing for a greater distance between them.

Based on the context of the experiment where Jasmine adds varying amounts of ice to samples of water, the most appropriate conclusion she could draw is:
**"As ice added increases, the change in water temperature increases."**
This conclusion makes sense because adding more ice typically results in a greater cooling effect on the water, leading to a more significant decrease in water temperature.
Let's briefly evaluate the other conclusions for clarity:
1. **"As ice added decreases, the water temperature decreases."** - This is contradictory, as less ice would generally lead to less cooling.
2. **"As water temperature decreases, the water molecules’ kinetic energy increases."** - This is incorrect, as a decrease in temperature generally corresponds to a decrease in the kinetic energy of the molecules.
3. **"As water temperature increases, the water molecules’ kinetic energy decreases."** - This is also incorrect; an increase in temperature means an increase in molecular kinetic energy.
In summary, the correct conclusion that Jasmine can draw from her experiment is that adding more ice leads to a greater change in water temperature due to the cooling effect of ice melting and absorbing heat from the water.

In the described experiment, the **independent variable** is the **number of ice cubes added**.
The independent variable is the factor that the researcher changes or manipulates in an experiment to observe the effect on the dependent variable, which in this case would be the change in temperature of the water in each container.
The other options (time elapsed, final water temperature, and initial water temperature) are not the factors being changed by the student. Instead, they are either constants or the outcomes measured in response to the independent variable.

The two statements that explain why the red-colored water from the small container rises to the top of the cold water are:
1. **"because the hot water is less dense than the cold water."**
2. **"because the hot water molecules move faster than those of cold water."**
Hot water is less dense than cold water because the molecules are moving faster and are more spread out, allowing the hot water to rise above the cold water. This phenomenon is a result of the differences in density between the two water states.

The correct response is:
**"The heat energy moves from the hot water into the cold water."**
Heat energy always moves from an area of higher temperature (hot water) to an area of lower temperature (cold water) until thermal equilibrium is reached.
**"The heat energy moves from the hot water into the cold water."**
Heat energy always moves from an area of higher temperature (hot water) to an area of lower temperature (cold water) until thermal equilibrium is reached.

The statement that best explains the result is:
**"Heated gases have higher kinetic energy and decreased density."**
When gases are heated, their molecules move faster, resulting in higher kinetic energy. As the temperature increases, the gas molecules tend to spread out, which decreases the overall density of the gas. This decreased density causes the heated gases to rise within their container.
