Well i agree what chintoo hav said papers were tough and entirely somewhat out of course. But nonetheless i still managed to ride the storm. Paper 2 in my opinion was jus i dont knw what to say.... Bambozzled.
Anyways i attempted the activation energy question and the question regarding luminisce and gels.
In luminisce i gave those examples which came into my mind like biolumini sonolumini piezolumini n what not and regarding gels i jus stated what they are like a semi solid mass with water and they are classifed physically n chemically n then mentioned some of them like silica gel cooling gel hair gel and cement gel whatnot.
