I don't really know what exothermic or endothermic is, but it still made me giggle.

Exothermic means that it gives off heat; endothermic means that it sucks heat in.

However, I could have that the wrong way round, like absorption and adsorption. Or was it apsorption? Ack.

Er..so, b implies some sort of interior assimilation of a foreign substance whereas d means it's just smeared on the outside?

(I'm not trying to be funny; chemistry was never my best subject so I'm trying hard to understand, honest!)

We never do stop learning, do we?

Thanks! I had a vague idea that's what it meant - but I was too lazy to look it up :)

Exothermic = that releases heat. Endothermic = that contains heat.
