Convection is a means of heat transfer that involves fluids, such as liquids or gasses. the process of convection is responsible for air and water currents as in the illustration. as the temperature of fluids increases their molecular motion increases, therefore as fluids warm their density decreases.
a classroom demonstration of convection involves placing a small covered container filled with warm water to which food coloring has been added into a large container of cold water.
based on the information in the prompt, select the observations that would be expected in this demonstration.
the warm water will rise out of its container when uncovered.
the cold water will flow into the container of warm water.
the warm water will sink as it cools.
the temperature of the warm water will decrease to the initial temperature of the cold water.
eventually all of the water will reach thermal equilibrium.
the final temperature will be the average of both initial temperatures.
