TIA.

Then the leaf will absorb water if it does not photosynthesise it will not be able to get rid of the water. The green parts will photosynthesise so water will not enter, causing leaf to be lighter and float. :?

Nebbermind:

For the melting ice problem, shdn't it be :


remain, remain & decrease? (since it stated 'melting ice', so water must be '0')

Ice will remain the same since it is melting at 0 degrees. Water will gain temperature since it's not melting :imcool:
