Is gauze a poor conductor of heat
Wire gauze or wire mesh can be described as a gauze woven of metal wire, or very fine, gauze-like wire netting. Wire gauze is placed on the support ring that is attached to the retort stand between a burner and glassware, or is placed on a tripod to support beakers, flasks, or other glassware to protect it during heating. Glassware should not be heated directly by the flame of a Bunsen or other gas burner; wire gauze diffuses the heat and protects the glassware. Glassware has to be flat-bo… WebNon-metals and gases are usually poor conductors. Poor conductors are called insulators . Heat energy is conducted from the hot end of an object to the cold end.
