A. and D. would be the best pick for this sort of experiment, but maybe (unlikely) B. because you could see how they could react in certain situations, how they react to danger but I suggest A.
Hope this helps you ☁︎☀︎☁︎
Explanation:
if we fix the temperature, we are just left with PV = constant for the gas law. So, in this situation, if the volume is doubled, the pressure must go down by one-half. And vice-versa. The simplest illustration of this would be a cylinder with a plunger on one end: if you push the plunger in so that the volume of the cylinder is halved and the temperature remains constant, then the pressure will double.
Mendeleev’s arrangement of elements in the periodic table was based on the observations and experiments of his predecessors who studied mass and properties of elements is TRUE.
<u>Explanation:</u>
In Mendeleev’s periodic table, elements were ordered according to their atomic masses. This is the fundamental property on which Mendeleev's periodic table is based on.
Mendeleev has also formulated a periodic law which states that the properties of elements are the "periodic function of their atomic masses". However, due to the anomalies that were created in his periodic table, we don't use this periodic table and prefer modern periodic table that is based on property of atomic number.
