Where do you measure the temperature when checking furnace temperature rise?

The rise in Air temperature is the difference between heated supply of air from the furnace and temperature of the return.

Explanation:

The temperature of the furnace should be kept within the plates range. Temperature rise of the furnace should be measured while the installation. The outside air temperature of the furnace is easy to measure whereas inside temperature is more difficult to measure. An excessive temperature rise in the furnace could cause combustion problem.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
