Explanation:
Dalton turned Democritus' views on atoms into a scientific theory by employing experimental methods. Atoms can join or detach during chemical processes, but they never transform into a different atom.
Dalton was an excellent polymath, a natural philosopher, and a real scientist. His thorough investigations prompted him to suggest an early atomic theory for which exceptions would be difficult to uncover today:
Dalton offered the following:
Atoms are microscopic particles that make up elements. Atoms of the same element have the same size and mass; however, atoms of other elements have varying sizes and masses when compared to atoms of other elements. Subdivision, creation, and destruction of atoms are all impossible.
All of these ideas were developed after a great deal of testing. Other researchers may replicate his work, and new findings could be included into this atomic idea.
Democritus, on the other hand, was a 5th-century BC Greek philosopher. He conducted no experimental work as far as we know, and none of his publications have survived. He postulated that matter was made up of a single indivisible element known as an atom; the word atom originates from the Greek word oos, which meaning "uncuttable" or "indivisible." So the name atom might be a homage to Democritus.

I think it is iron conducts electricity and heat
The students can determine which of the solutions contains salt through the conductive tester.
<h3 /><h3>What is an ionic solution?</h3>
It is a solution containing ions are atoms that have gained or lost electrons to acquire a positive (lost electron) or negative (gained electron) charge.
An ionic solution would be able to conduct electricity whereas the covalent would not so if you have a conductivity tester which is available in most labs.
The students can distinguish between the 2 solutions through the conductive tester.

The independent variable (x-axis) is what the scientist (or supervisor) can change themselves while the dependent variable (y-axis) is the result of the independent.
Note, just like how you graph a coordinate, you would go along the x-axis, which is the independent variable, and from there, you go up or down the y-axis because of the dependent variable.
e.g. The height of a plant DEPENDS on how much fertilizer the farmer give it.
The independent is the amount of fertilizer, because the farmer could control how much they give, and the height of the plant is the dependent variable because it depends on the independent variable.
