Hi!
Basically convection is the transfer of thermal energy through fluids. Examples would be air and water.
Convection waves are invisible: You can't see them.

In convection less molecules occupy large volume as in air to reduce the density.
Radiation
Lack of a flow medium will inhibit conduction and convection.

solids have particles that are closely packed together and cannot move freely, which inhibits the transfer of heat through convection. Convection relies on the movement of particles to transfer heat, and in solids, this movement is limited. Therefore, heat transfer in solids primarily occurs through conduction.
I'm looking for the exact same answer! I HAVE NO IDEA!!! xx
Replacing a microwave with a convection microwave is an excellent idea. It allows you to cook items as if they were in a conventional oven which can be handy if you don't want to heat up the house or you need extra space to cook in.
Convection
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
The scientific name for convection is "convection."
convection
Normal convection occurs naturally due to temperature differences, while forced convection is induced by external means such as fans or pumps. Forced convection typically has higher heat transfer rates compared to natural convection due to the enhanced fluid motion generated by the external force.
The three main types of convection are natural convection, forced convection, and mixed convection. Natural convection occurs due to density differences caused by temperature variations. Forced convection involves the use of external means like fans or pumps to enhance fluid movement. Mixed convection combines both natural and forced convection mechanisms.
Conduction
Convection occurs in the atmosphere due to temperature differences between the Earth's surface and the air above it. As the Sun heats the surface, the air near the surface becomes warmer and less dense, causing it to rise. This creates vertical air currents and leads to the circulation of air in the atmosphere.
