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.
Complete Question
A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 74.0 wide. The biologist estimates she will need 2600 L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Round your answer to significant digits.
Answer:
The pressure required is
Explanation:
Generally the volume of a sphere is mathematically denoted as
Substituting
Converting to Liters
Assume that the pressure at which the air is given to the diver is 1 atm when the air was occupying a volume of 2600L
So
From Charles law
Substituting , , , and making the subject we have
Answer: B) Wood Shavings
Reason/Explanation:
Notice what options A, C, and D have on common. Ice, salt and sugar. Those are all dissolvable. Insoluble means un-able to dissolve. It can't dissolve. Wood shavings can't dissolve in water. They will just float. Sugar, salt and ice will all dissolve. Wood shavings won't.

Answer/Explanation:
f is the number of waves produced by a source per second, it is measured in hertz (Hz). T is the time it takes for one complete oscillation, it is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. A radio wave has a time period of 0.0000003333333 seconds.
