Why did the food coloring spread faster in hot water than in the cold water?

• Because hot particles are bigger than cold particles.

• Because the teacher stirred the hot one but not the cold one.

• Because hot particles are moving faster than cold particles.

• Because cold particles are moving faster than hot particles.

What type of heat transfer is occurring in the example below:

You buy a lava lamp from the store. As the lamp heats up, blobs of hot liquid rise to the top and cold liquids sink back down to the bottom.

• Conduction

• Convection

• Radiation
