We wait a little after changing the volume of the trapped gas, to make sure that is the gas is back to room temperature.
<h3>
Boyle's law</h3>
This law states that the volume of a fixed mass of a gas is inversely proportional to its pressure provided that temperature remains constant.
P₁V₁ = P₂V₂
<h3>Why we wait a little </h3>
We wait a little after changing the volume of the trapped gas, to make sure that is the gas is back to room temperature because a change in temperature can alter the accuracy of the experiment.

Answer:
The correct answer in which peer forces each act in a different body
Explanation:
Newton's law of action and reaction states that the two forces have equal magnitude, but in the opposite direction, each acting on a body. Which creates acceleration in these, if they act in the same body it would be canceled so there would be no movement.
The correct answer in which peer forces each act in a different body
B.Sunlight because and what do you not understand. I'll help you with it
Answer:
D=M/V. That's the formula. Density is expressed, in cubic centimeters.

Answer:
Different wavelengths of light also have different frequencies, so the "individual" waves of light are different.
So when you see a given spectra, you are actually watching a superposition of different light waves, and as the waves do not interact that much between them, you can see the different colors.
You can think this similarly as the case with two different sound waves, one high in pitch, and another low.
You can easily identify them, as they do not collide between them.
Now, if you are asking "why the spectrum has different colors".
This is because the levels of energy in each element are different, the outer electrons have weaker bonds, so they will emit photons with less energy (larger wavelength) and so on.
So there are multiple wavelengths because electrons with stronger and weaker bonds are jumping between states at the same time.
