Ok thanks, but I don\'t think we are meant to use that because it\'s not given..I think we have to derive it somehow?
You definitely don't need to derive the equation for hawking radiation. I can't think of any other temperature they might be referring to....

So I see that the entropy will increase because A increases..and I can work out the entropy change..but what does it mean \"in equivalent bits of info\"? THanks!
Great. 'in bits' just means using a particular unit of measurement of entropy. I'm not sure if you're familiar with any computer-science, but its the same 'bit'---referring to a single piece of information (yes or no; 0 or 1). You'd have to check your formula to see what units its in---I'm not sure off hand. I'm sure google could find out.
