Tile Roofing Prices. On average, tile roofs cost $700 to $800 per square to install, though they can cost anywhere between $400 and $1,000 per square. Tiles come in clay or concrete but can be shaped in many different ways even to the point of looking like wood shake.
Heat Convection. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law).
Conduction is when heat is transferred through a material by passing thermal energy from molecule to molecule (from collisions). An example is when you heat up one end of a pa â¦ n and the handle gets hot a little later. Convection is when, as they say, heat rises.onduction:-   Conduction is the transfer heat from a hotter to a colder body by  vibrating.   Convection:-   Is the main heat transfer mechanism in fluids.
