is that brittle is inflexible, liable to break or snap easily under stress or pressure while flexible is capable of being flexed or bent without breaking; able to be turned, bowed, or twisted, without breaking; pliable; not stiff or brittle.s that brittle is (uncountable) a confection of caramelized sugar and nuts while flexible is (chiefly|engineering|and|manufacturing) something that is flexible. As adjectives the difference between brittle and flexible. As nouns the difference between brittle and flexible.
If you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to Charles's law. In this case, volume will also decrease. If you were to maintain a constant volume while decreasing the temperature, the pressure would also have to decrease in order to satisfy Gay-Lussac's law.
This is the same thing as asking what happens if you change the Pressure of air. Use Boyle's law of vapor pressure to determine the answer which is: V1P1/T1 = V2P2/T2 In which, P2 is the vapor pressure (partial pressure) after some of the oxygen has reacted with the iron. If we assume that Temperature and Volume of vessel are constant, then you can see by the equation, that the pressure will drop (it will decrease).
