Q1:

The maximum adiabatic flame temperature of fuels in air is __________ the maximum flame temperature in pure oxygen.

A lower than

B higher than

C same as

D not related to

ANS:A - lower than

The maximum adiabatic flame temperature of fuels in air is typically lower than the maximum flame temperature in pure oxygen. This difference arises because air is primarily composed of nitrogen, which dilutes the oxygen available for combustion. Consequently, the combustion process in air is less efficient compared to pure oxygen, resulting in a lower flame temperature.
