Jasmine adds varying amounts of ice to samples of water. Which conclusion can she draw from her experiment?(1 point)
As water temperature increases, the water molecules’ kinetic energy decreases.
As water temperature increases, the water molecules’ kinetic energy decreases.
As water temperature decreases, the water molecules’ kinetic energy increases.
As water temperature decreases, the water molecules’ kinetic energy increases.
As ice added decreases, the water temperature decreases.
As ice added decreases, the water temperature decreases.
As ice added increases, the change in water temperature increases.
The correct conclusion that Jasmine can draw from her experiment is:
- "As ice added increases, the change in water temperature decreases."
Bot, it says, "As ice added increases, the change in water temperature increases."
It does'nt say "decreases"
I apologize for the mistake in my previous response. You are correct. The correct conclusion is:
"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)
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 is more dense than the cold water
because the hot water is more dense than the cold water
because the hot water is less dense than the cold water
because the hot water is less 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 as fast as those of cold water
because the hot water molecules move as fast as those of cold water
The correct statements that explain why the red colored water from the small container rises up to the top of the cold water are:
- "because the hot water is less dense than the cold water"
- "because the hot water molecules move faster than those of cold water"
If a mixture of different gases is heated, it rises to the top of its container. Which statement best explains this result?(1 point)
Responses
Heated gases have lower kinetic energy and lower density.
Heated gases have lower kinetic energy and lower density.
Heated gases have lower kinetic energy and higher density.
Heated gases have lower kinetic energy and higher density.
Heated gases have higher kinetic energy and higher density.
Heated gases have higher kinetic energy and higher density.
Heated gases have higher kinetic energy and decreased density.
The correct statement that best explains why a mixture of different gases rises to the top of its container when heated is:
"Heated gases have higher kinetic energy and decreased density."
To draw a conclusion from Jasmine's experiment, we would need more information about the experiment design, goals, and measurements taken. However, based on the given information, it is unclear what specific conclusions can be drawn.
If Jasmine's intention was to observe the effect of adding varying amounts of ice to water, here's what she could consider:
1. Temperature change: Jasmine could measure the change in temperature of the water after adding different amounts of ice. If the temperature decreases consistently with increasing ice, she can conclude that adding more ice lowers the temperature of the water.
2. Dilution: Jasmine could measure changes in the concentration of solutes in the water. If adding more ice leads to greater dilution, she could conclude that adding ice increases the water's volume or decreases the concentration of dissolved substances.
3. Phase change: Jasmine could observe whether any ice remains after adding it to water and mixing. If ice completely melts in all samples, she could conclude that the ice melts in contact with water at the given conditions.
In order to draw valid conclusions, it's important to control other variables (e.g., initial water temperature, volume of water, time of observation, etc.) and repeat each experiment multiple times.
