The answer is C. Compressing the air reduces the volume and increases the pressure. Compressing the air causes the molecules to collide with one another, and with the walls of the container, at a higher frequency. This is becaue the number of molecules are still the same but now forced in a smaller volume of space. This why the pressure increases wiht reduced volume, while keeping the temperatures constant.

Answer: option C. Increasing the pressure on a gas decreases the volume.

Explanation:

Compressibility is the property of matter that relates the change (decrease) of volume under pressure (compression).

It is defined as the relative change in volume compared to a change in pressure.

Gases under normal conditions of pressure and temperature are highly compressible, since the molecules are widely separated.

You can see the inverse relation between pressure and volume in a gas by looking at the ideal gas equation:

pV = nRT

Hence, constant n, R and T means pV = constant, so as p increases V decreases, which leads to the conclusion stated by the option C: increasing the pressure on a gas decreases the volume.

1)Which of the following changes would decrease the rate at which a solid solute dissolves in a liquid solvent? (3 points)
Diano4ka-milaya [45]

Answer:

The first one is B, "Decreasing surface area."

Explanation:

This is because greater the surface area exposed, the more collisions that occur between the solvent and solute. I also just took the test myself and got it correct.

Answer:

- The chemical reaction is not balanced. There is two oxygens on the reactant's side while there's only one oxygen on the products side.

- I would not say it's following the law of conservation of mass as it's not a balanced equation.

- To balance this equation, you would need to add the coefficient of '2' to Magnesium (Mg) on the reactants side, and add the coefficient of '2' to the products side.  This would make it so that there's 2 Mg's and 2 O's on both the reactant's side and products side.

edit: I hope this helped you in some way. ^^

What is 1 major discovery in cosmology that relies on improvement in existing apparatus?
never [62]
The most dramatic astronomical development of the century thus far is the detection of gravitational waves from merging black holes at a distance of 400 Mpc, during the first science run of the advanced Laser Interferometer Gravitational-Wave Observatory.

The telescope was also very important. Galileo Galilei was the first person to use a telescope to look at celestial bodies (though he did not invent the telescope) and discovered the four brightest moons of Jupiter, proving that there are things in the Solar System that don't revolve around the Sun.

Physical cosmology is the branch of physics and astrophysics that deals with the study of the physical origins and evolution of the Universe. It also includes the study of the nature of the Universe on a large scale. In its earliest form, it was what is now known as "celestial mechanics", the study of the heavens.

Hope this helps you :)
