Only one: the nucleus of an atom is made up of protons and neutrons.
Why others are false:
Boiling point of a substance is not dependent on the volume because it’s a intensive property.
During sublimation, a solid changes directly into gas.
Electrons orbit the nucleus of an atom in circular orbits (kinda unsure of this one.)
Answer:
5.0g/cm^3
Explanation:
Since we have the mass of the wood (25.0g) and the volume of the wood (5.0cm^3), can use the formula for density to answer this question.
Density=mass/density
Density=25.0g/5.0cm^3
Density=5.0g/cm^3
Therefore, the density of the piece of wood is 5.0g/cm^3.
I hope this helps!
<u>A superfluid is a state of matter in which matter behaves like a fluid with zero viscosity</u><u> </u><u>The substance, which looks like a normal liquid, flows without friction past any surface, which allows it to continue to circulate over obstructions and through pores in containers which hold it, subject only to its own inertia.</u>
The independent variable as we can see from the experiment that have been described in this case is the brand of fertilizer that was used in the study.
<h3>What is an experiment?</h3>
When we talk about an experiment, we are talking about the way by which the relation ship between the dependent and the independent variable could be studied. In the experiment, there is a dependent variable which would change values when the variable that is under study in the particular experiment changes value. We have to know that in the realm if science, it is only by the means of experiments that we can be able to establish cause and effect relationships.
In this case, we can see that the experiment that the students were working on has to do with trying to actually find out if brand X fertilizer will affect the growth of Lily plants. This means that they were studying the effect of a fertilizer brand on the growth of the crops.
