Through convection, as the liquid toward the bottom of a container warms up, it becomes less dense and moves to the top, allowing a cooler section of the liquid to contact the heating source. This ...

If you have a shiny new convection oven on your counter, or a wall oven that includes convection capabilities, you may be thinking, “Cool! But what does the convection setting do?” That’s a good ...

Everyone knows the saying “heat rises,” right? Why does heat rise? Let’s use the example of water in a pot. Take a pot full of cold water and place it on a stove. Turn the heat on, and the water near ...

Walk into almost any modern kitchen, and you will likely find an oven with more than one cooking mode. Alongside the familiar bake and broil settings, many ovens now include a convection option.

In this activity from Lawrence Hall of Science, you’ll use hot and cold water to see how fluids at different temperatures move around in convection currents. Be sure to share what you’ve learned about ...

Findings from a table-top experiment have revealed that the primary driver of a type of fluid flow called solutal convection has been overlooked. What's more, once this driver is accounted for, it ...
