Likely the reason behind carrying them in liquid for is to condense them. liquid takes up far less space than gases do and will last far longer. they can be transformed back into gases through heating them back up. To keep them solid would require frigid temperatures but liquid will transfer more easily through space.

The densities of various substances are listed in the chart. All of these substances have the same

Butoxors [25]

Answer:

The object with the greatest density

Explanation:

The object that will have the greatest mass from the given choices is the one with greatest density.

Density is the mass per unit volume of a substance;

Density = $\frac{mass}{volume}$

We can see that density is directly proportional to the mass and inversely proportional to the volume.

The more the mass and the lesser the volume, the higher the density.

So, since the volume is the same, and mass is directly proportional to density, the object having the highest density will have the greatest mass.
