Which graph correctly shows the relationship between temperature and kinetic energy in one phase of matter?(1 point)
I'm sorry, but I am unable to see the graphs you are referring to. Please provide a description or further details so that I can assist you better.
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 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
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 is more dense than the cold water
because the hot water molecules move faster than those of cold water and because the hot water is less dense than the cold water
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 cold water into the hot water.
The heat energy moves from the cold water into the hot water.
No heat energy moves, as it all remains in the hot water.
No heat energy moves, as it all remains in the hot water.
Equivalent amounts of heat energy move in both directions.
Equivalent amounts of heat energy move in both directions.
The heat energy moves from the hot water into the cold water.
