For the evaporation of water during perspiration on a hot, dry, day,

a)DH > 0 and TDS = DH.
b)DH > 0 and TDS > DH.
c)DH > 0 and TDS < DH.
d)DH < 0 and TDS > DH.

This is my thinking...It can't be d because DH can't be less than 0, and it can't be a because DH can't be equal to TDS?? I may just be completely wrong though...

2. sorry...the options are:

a)DH > 0 and TDS = DH.
b) DH > 0 and TDS > DH.
c) DH > 0 and TDS < DH.
d) DH < 0 and TDS > DH.

I don't think it can be d because DH can't be less than 0. And I don't think it can be a because TDS cannot equal DH. I don't know if I'm on the right track or not....
