1. Compressibility is the how much the volume of a gas can shrink under pressure. This affects the behavior of the gas by determining how tightly it can be packed.
2. A ballast tank in a submarine is used to make the submarine dive or rise. It changes the amount of water in it, which changes the ...

1. I got about 3.87:
8.7 x 10^5 micrometers = .87 meters
.87/2 = .435 (radius)
.435^3 = about .0823
.0823(pi) = about .259
The volume of the sphere is about .259 cubic meters
Therefore it is about 259,000 mL
The mass of the ball is 1 kg
Therefore it is 1,000,000 mg
1,000,000/259,000 = about 3.86 ...

1. A ball with diameter 8.7 x 10^5 micrometers has a mass of 1 kg. What is its density in mg/mL?
2. A weight made of lead is tied to a scale which reads 5 kg. When the weight is completely submerged in water, the scale reads 4.559 kg. What is the volume of the weight in cubic cm?
3. An iceberg (0 ...

On #2 do the objects take up the entire tray?
On #4 I don’t think you can calculate the impact force without the height the tennis ball falls from.
On #4 To my understanding of pressure, we can’t figure out the pressure of the tennis ball on the court without knowing how much of the tennis ball ...

Those are all correct! I was just a little confused when no one answered my questions after four days since usually it takes one or two days for an answer.

If nobody is going to answer by the 16th, I will answer them myself.

I guess I will go then.
1) A ball of an unknown material has a density of 16.3g/cm^3. It is placed in a bowl of water and the volume of the water goes up from 400mL to 800mL. What is the mass of the ball?
2) What is Gay Lussac’s Law? Provide an example question with an answer.
3) The pressure ...

Here’s my work for 1 and 3. Correct me if I am wrong:
1:
70 picometers = 7e^-11
Volume of a sphere = 4/3(pi)(r
4/3(pi)(3.43e^-31) = approximately 1.436755e^30
That is the volume of one atom.
1.436755e^-30(3.50)(10^6) = 5.0286426e^-24
I recalculated and got 5.0286426e^-24. I guess I forgot to cube ...
