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 less dense than the cold water
because the hot water is less dense than the 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 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 has the same density as the cold water
because the hot water has the same density as the cold water
because the hot water is less dense than the cold water and because the hot water molecules move faster than those of cold water
The correct conclusion that Jasmine can draw from her experiment is:
"As ice added decreases, the water temperature decreases."
To determine the conclusion that Jasmine can draw from her experiment, we need to analyze the relationship between the amount of ice added and the change in water temperature. By systematically adding varying amounts of ice to water samples, Jasmine can observe how the temperature of the water changes.
To find the correct conclusion, we should look for a pattern in her observations. One way to do this is to compare the amount of ice added with the change in water temperature.
If Jasmine finds that as she adds more ice, the temperature of the water decreases, then she can conclude that "as ice added increases, the change in water temperature increases."
However, if Jasmine finds that as she adds less ice, the temperature of the water decreases, then her conclusion would be "as ice added decreases, the water temperature decreases."
It's important to interpret the observations accurately to determine the correct conclusion in this experiment.
