hot air oven heats content in it and where as furnace heats air around it

Standard operating procedure for hot air oven operation
The principle of a hot air oven is to circulate hot air in a controlled manner to create a uniform temperature distribution within the oven. This ensures consistent heating of the contents inside the oven. Hot air ovens are commonly used for sterilization, drying, and heating applications in laboratories and industrial settings.
Convection oven.
A convection oven.
In a hot oven, the air molecules gain energy and move more rapidly, causing the air to expand and become less dense. This results in convection currents where the hot air rises, creating circulation within the oven that helps cook the food more evenly.
The hot-air balloon was invented in 1783.
they invented there hot air baloons in France where they grew up..
it's a fan inside an oven, used to circulate the hot air. It's generally found in a convection oven.
A hot air oven is commonly used for sterilizing equipment and materials in laboratories and industries. It works by heating objects through hot air circulation at a controlled temperature, effectively killing bacteria, viruses, and other contaminants. This method provides a dry heat sterilization process that can reach high temperatures to ensure thorough sterilization.
If you ever want to measure a temperature above 212 degrees, you're better off hanging the thermometer into the air in the oven. Since it's a hot-air oven, you want to measure the air. If it were a hot-water oven, you might prefer to measure water. But even then, what are you gonna do above 212, when the water goes away and all you have in there is steam ??
