Which conditions relate to the research of van Helmont?

plant mass related only to soil

conclusions partly correct

demonstrated plant food from soil

conducted around 1400 A. D.

plant mass related to H 2O

Hello, I see that you are studying Jan Baptist van Helmont, founder of pneumatic chemistry. I assume that you are studying gases and how plants work.

van Helmont, in his experiment studied the theory of how "plants grow while eating soil." Weird right? He put a willow tree in soil, but before doing that, weighted the soil. After 5 years of seeing the same mass of soil, he concluded that plants grew by drinking water.

So the answer would be:

- Plant mass is related to H₂O

- Conclusions partially correct.
