Answer:
the relative density of the gravel in the field is 0.7365 or 73.65%
Explanation:
Given that;
wet density of gravel 
= 2.3 Mg/m³
field water content w = 16%
density of solids in lab 
= 2.70 Mg/m³
Maximum void ratio 
= 0.59
Minimum void ratio 
= 0.28
first we determine the dry density of gravel 
= / 1+ w
= 2.3 Mg/m³ / 1 + 0.16 = 2.3/1.16 = 1.9827 Mg/m³
we know that; 
= 1000 kg/m³ = 1 g/cm³
Specific Gravity of soil G = / = 2.70 Mg/m³ / 1 = 2.70 Mg/m³
eo = ((G×)/) - 1
eo = (( 2.70 × 1) / 1.9827 ) - 1
eo = 1.3617 - 1
Co = 0.3617
so Relative density 
will be;
= - eo / -
we substitute
= 0.59 - 0.3617 / 0.59 - 0.28
= 0.2283 / 0.31
= 0.7365 or 73.65%
Therefore; the relative density of the gravel in the field is 0.7365 or 73.65%
Less gas will be collected because some of the gases will escape from the open cylinder valve.
Cylinders used to store carbon dioxide will have thicker walls than those of butane because of higher pressures.
<h3>What are compressed gases?</h3>
Compressed gases are gases which are compressed under high pressure in gas cylinders.
Cylinder valves are used to reduce the pressure of the compressed gases and in the process, some of the gas molecules escape.
Since the cylinder valve is open and the gas is collected at atmospheric pressure, less gas will be collected because some of the gases will escape.
Since, the carbon dioxide not liquefy under pressure compared to butane, the cylinders used to store carbon dioxide will have thicker walls than those of butane.

It gets larger because
well let me give you an example
so today in class we looked at a lava lamp with wax inside and there was a lightbulb at the bottom.
we watched as the wax floated up because the molecules inside the wax spreads out and makes the wax less dense.
the wax floats up because (which is related to the balloon getting bigger) the wax is getting less dense and the particles get bigger which ALSO makes the wax less dense.
hope this helps and hope you can relate it to your problem! say thanks if I did help AT ALL! :)
