A tire has a volume of 3 ft3 and a gage pressure of 32 psi at 75 o F. If the ambient pressure is sea-level standard, how much does the air in the tire weigh

Explanation:

Relation between density and pressure is as follows.

         P =

            = 6724.8

Value of R = 1716

           T =

Now, we will calculate the density as follows.

                        = 0.007325

Therefore, density of the air is 0.007325 .

Now, we will calculate the weight of the air as follows.

           W =

               =

               = 0.215 lbf

Therefore, weight of the tire in air is 0.215 lbf.

do you have a formula possibly

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
