Answser: a curved line.
Justification:
Boyle's law states that a constant temperature the volume of a certain amount of gas is inversely related to the pressure:<em> pV = k.</em>
The graph of two inverseley related variables is a curve: as one variable increases the other decresases.
In such a curve for any pair of points it is obeyed Boyle's law: pV = constant, so:
<em> p₁V₁ = p₂V₂ = p₃V₃ = ... = k</em>
Mathematically, the graph represents a hyperbola: as the value of one of the variables increase the other trends to zero, so the curve approaches the axis without touching them.
See the figure attached to visualize the form of the curve.
The answer is A, when these particles are heated they tend to speed up.
Answer: The positive and negative charges of the water molecule pull on the negative and positive ends of the ionic molecule to break them apart.
Explanation:
Ionic compounds dissolve in polar solvents such as water as like dissolves like. Ionic compounds are made up of ions which remain attracted by coloumbic forces.
Thus to separate the ions, the positive and negative charges of polar solvent pulls the opposite charges of the ionic compounds and thus break them apart. Thus the ionic compounds dissolve in water.
