What is the primary way heat is transferred through fluids like air and water?

• Conduction

• Radiation

• Convection

• Evaporation

What property of fluids causes them to move and transfer heat in convection?

• Volume

• Mass

• Temperature

• Density

How does the density of cold water compare to hot water?

• Cold water is less dense than hot water.

• Cold water is more dense than hot water.

• Cold water and hot water have the same density.

• Density of water does not change with temperature.

When cold, blue-colored water was released at the bottom of a container of cool tap water, what was observed?

• The blue water quickly rose to the top.

• The blue water mixed evenly with the tap water.

• The blue water stayed at the bottom of the container.

• The blue water evaporated immediately.

What happens to warm fluids during the process of convection?

• They become more dense and sink.

• They become less dense and rise.

• They remain at the same level.

• They change into a solid state.
