User: Ratnadeep Sircar Hello David, You´re anbsoloutely right, I didn´t read rhe question properly. A friend posed this question to me as " what would the potatoes weigh, if 1% of the water evaporates? ". I have deleted my comments on the main page and would like to apologize to anybody who was offended by them. The equations are correct.
All the same, it leads to another thought: When the water evaporates , the space it occupied would probably, if only partially, be replaced by air. This would mean that the total mass would be higher, as that which is presumed in the solution. As a result one would have to modify the equations and would end up with another result. What do you think about this?
