all of these
funny im doing it right now
The main method of thermal transference in the atmosphere is convection, conduction would only account for a fraction. Conduction works via hotter molecules transferring their energy to cooler molecules via the friction of collisions between molecules. As air has a very low molecular density conduction is poor therefore most atmospheric models will ignore it.
It doesn't work that way - friction is not something that is "produced". The way it works is that you have a coefficient of friction for two surfaces that are in contact. Then you use that coefficient of friction, and multiply it by the normal force, to calculate the actual FORCE of friction.For the coefficient of friction, you need to specify a PAIR of substances; for example, carpet against glass would probably have less friction than carpet against rubber.
There are many applications that would benefit from less friction. Any kind of motion where heat is produced but not intended would benefit from less friction. Some examples: 1. the contact point between the piston and wall in an engine produces less heat and more power with less friction 2. air flow over a car's exterior, over a plane's exterior, over a rockets exterior results in reduced drag (air resistance) with less friction 3. the space shuttle could definitely use less friction with the atmosphere during re-rentry 4. electrical conductors are more efficient as friction decreases 5. if friction were 0, the perpetual motion machine would be possible
Without friction it would be impossible to stand, you would instantly fall down flat. Without friction it would be impossible to crawl. Without friction the only way it would be possible to move would be by using thruster jets, as they do on spaceships.
cooking grilled meat would use radiation some convection. conduction would cook the inside.
When you put hot coffee into a mug, the heat is transfered by CONDUCTION since they are in direct contact with each other.

Ways that friction are beneficial: Standing - Friction allows you to stay in position instead of moving around even when you do not want to Braking of cars - Similarly, friction makes it possible to make a car stop Ways that friction is nuisance: Wear and tear - Friction produces heat, which would flatten shoe soles, smoothing the gears or other mechanics in machineries

Yes, since there would be no conduction of sound in a vacuum.
NO friction
It is impossible to have no friction. If there was no friction we would be sliding all over the place, nothing would be balanced.
A synonym for friction would rub. :DA synonym for friction would rub. :D

Conduction works quite well in the gas inside a fluorescent light tube.
