Heat transfer by conduction is not possible for gases?

Rapid heating of the gas region may generate a shock wave whose propagation temperature rises and the leading edge of the shock wave is regarded as a boundary or a container with the sound speed in the gas and the depth and the density are the temperature according to Boyle's law It is affected by the rise. (And then, as the elasticity of the gas allows it, there are decreases in amplitude reduced waves, wave pressure wave increase etc).

In closed vessels, which are much smaller than the sound speed in the gaseous medium, the equilibrium speed is very fast, which is much faster than Brownian motion and separate convection.

Conduction is a heat transfer process occurring in solids, liquids, and gases. In the process of conducting energy, higher energy molecules collide with lower energy molecules. In solids, molecules oscillate at lattice positions and transfer their energy from higher temperature molecules to lower energy molecules. In solid (metal), 70% of conduction occurs by electron transfer and 30% by molecular vibration. In metal, heat transfer is reduced with increasing temperature because molecular oscillation hinders electron transfer, but heat transfer increases with nonmetal as molecular oscillation increases. For gases and liquids, heat transfer also increases as the temperature rises.

Convection heat transfer, often referred to simply as convection, is the transfer of heat from one location to another due to fluid movement. Convection is usually the main form of liquid or gas heat transfer. Although generally discussed as a unique heat transfer method, convective heat transfer involves a combined process of unknown conduction (thermal diffusion) and flat flow (heat transfer through multiple fluid streams). Convection can be "forced" by movement of fluid by means other than buoyancy (eg, a water pump in a car engine). The thermal expansion of the fluid may also force convection. In other cases, when the fluid is heated, the individual natural buoyancy is fully responsible for the movement of the fluid and the process is called "natural convection". An example is a chimney or a draft around the fire.

Heat is transferred from one place to another in three ways. Solid conduction, convection of fluid (liquid or gas), and radiation that allows the passage of radiation. The method used for heat transfer is usually the most effective method. If there is a temperature difference in the system, the heat always moves from a higher temperature to a lower temperature. Conduction occurs when two objects at different temperatures are in contact with each other. Heat flows from a high temperature object to a low temperature object until it reaches the same temperature. Conduction is the movement of matter by collision of heat by molecules. When two objects are in contact, faster moving molecules of warmer objects collide with slower moving molecules of cooler objects. On impact, faster molecules emit energy to slower molecules. Slower molecules get more heat and collide with other molecules with cooler objects
