Question

To investigate the factors affecting the rate of transpiration in plants, students set up two distinct experiments using identical bean plants.

In Experiment 1, three plants were placed in separate chambers with varying levels of relative humidity ($30\%$, $50\%$, and $70\%$) at a constant temperature of $22^\circ\text{C}$ and a constant light intensity of $800\text{ lux}$. The mass of water lost by each plant was measured after 6 hours.

In Experiment 2, three plants were placed in separate chambers at varying temperatures ($18^\circ\text{C}$, $24^\circ\text{C}$, and $30^\circ\text{C}$) at a constant relative humidity of $50\%$ and a constant light intensity of $800\text{ lux}$. The mass of water lost by each plant was measured after 6 hours.

Determine whether the following statement is true or false:

The relative humidity of the environment in Experiment 2 was held constant at a value that was also tested as an experimental condition in Experiment 1.
