Heating water in a pot on the stove.
Stoves are designed to apply heat to the bottom of the pot, not to the top.
The reason for this is that hot water in the pot rises and cooler water in the
pot sinks. Convection keeps the water circulating in the pot, keeping the coldest
water on the bottom, and that's why we apply the heat there.
What else can I help you with?
How thick are the convection currents?
Convection currents can vary in thickness, typically ranging from a few centimeters to kilometers depending on the scale of the system in which they occur. In the Earth's mantle, for example, convection currents can be tens to hundreds of kilometers thick.
Is a campfire an example of a convection current?
Yes, a campfire is an example of a convection current. As the air closer to the fire heats up, it becomes less dense and rises while cooler, denser air moves in to replace it. This creates a circular flow of air known as convection.
What does convection look like?
Convection is the movement of fluid due to differences in temperature within the fluid. In a visual sense, convection can be observed as the rising and sinking of fluid in a liquid or gas due to temperature variations. For example, in a pot of boiling water, convection currents can be seen as the water near the heat source rises while cooler water sinks.
Are heat vents examples of forced or natural convection?
Heat vents are an example of forced convection. Forced convection occurs when a fluid motion is caused by an external source such as a fan or pump, as opposed to natural convection, which occurs due to density differences in the fluid. In the case of heat vents, the air is circulated by a fan to distribute the warm air throughout a room.
Does convection occur in the core of a star?
No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
What is a non-example of convection?
Adhesion is a non-example of convection.
What is a non example of convection?
Adhesion is a non-example of convection.
What is a convection example?
