CT: Conduction is another way that heat moves. Heat is a form of energy, and when it comes into contact with matter (Anything that you can touch physically) it makes the atoms and molecules move. Once atoms or molecules are moving, they collide with other atoms or molecules, making them move too. These, then bump into other molecules and make them move, too. In this way, the heat is transferred through matter.
Conduction is what makes the handle of a pot hot when only the bottom of the pot is touching the stove. The heat from the burner starts the molecules in contact with the burner start to move. Those molecules bump against others in the pot, which bump others, until all the molecules in the pot, including in the handle, are moving. When someone touches the pot handle, they feel the heat. The heat has moved from the burner to the cook’s hand through conduction.
Conduction is an important way that heat travels in space, but only within a spacecraft. Since there is very little matter in deep space, heat cannot leave a spacecraft by conduction.

N: 1. late 13c., also as a surname, Brenner, “person who makes bricks,” agent noun from burn (v.)). As a name for a part of a lamp where the flame is applied, from 1790. Of gas-cooking stoves, by 1885.
2. Burners for coal, oil, or gas are similar in that fuel is injected into the furnace through the center of the burner while air for combustion is supplied through an annulus. The fuel ignites in a fuel-rich center zone and combustion is completed in an outer zone where the remaining air is mixed in. To minimize the production of nitrogen oxides, staged air admission is arranged by having an additional air annulus. This reduces the concentration of oxygen at temperatures at which nitrogen oxides are formed.
