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.
Likewise, as elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation.he boiling point is the temperature at which the vapor pressure is equal to the atmospheric pressure around the water. Because of this, the boiling point of water is lower at lower pressure and higher at higher pressure.
