# Is there any example of convection that isn’t?

## What is convection without?

Non Explanation: Heat is transferred to the hamburger without direct contact. This is not convection. Through a fluid (gas, liquid).

Which is an example of convection current?

Convection Currents exist in the air. A good example is the warm air rising towards your ceiling. This happens because warm air is less dense than colder air. Wind is another example of convection current.

### Which is an example of convection currents Brainly?

marshmallows toasting over a campfire. A pot is being heated with an electric burner. Rice is heated in a pot. Radiator that draws in warm air while emitting warm air.

Which of the following describe the convection current?

Convection Currents are caused by differential heating. Warmer, lighter (less dense) material rises and cooler, heavier (more dense), material sinks. This movement creates convection currents, which are circulation patterns in the atmosphere, water, and mantle of Earth.

## What causes convection current?

Convection Currents are formed when a heated fluid expands and becomes less dense. The heat source is removed from the less dense heated fluid. It pulls down cooler fluid to replace the heat source as it rises. This cool fluid is then heated and rises, pulling down more cool fluid.

How do you create a convection current?

Make Convection Currents

1. Fill the plastic container 2/3 full of room temperature water.
2. Let the water sit for 30 seconds or until it is completely still.
3. Place a blue ice cube at one end of the plastic container.
4. Add two drops of red food coloring to the water at the opposite end of the plastic container.

### Which step is not part of a normal convection cycle?

Warmed air rises to create a high-pressure system. This is an exception to the normal convection cycle.

What are the examples of conduction convection and radiation?

Examples of conduction, convection and radiation

• Conduction: Touching a stove and being burned. Your hand cools down with ice.
• Convection: Hot air rising, cooling, and falling (convection currents)
