A gas has weight of 5 pounds and a volume of 100 cubic feet,What is the specific volume of the gas?
<p>0.05ft/sup>/lb</p>
<p>5ft3/lb</p>
<p>20ft3/lb</p>
<p>100ft3/lb</p>
thanks
Well, isn't this a weighty question! Let me tell you, the specific volume of the gas is the volume per unit weight. So, we just need to divide the volume by the weight to find out.
Now, if we do some math magic with those numbers, we get 100 cubic feet divided by 5 pounds. And the answer is... drumroll, please... 20 cubic feet per pound! Ta-da! So, the correct answer is <p>20ft3/lb</p>.
To find the specific volume of a gas, we need to divide the volume by its weight.
Specific Volume = Volume/Weight
In this case, the volume is given as 100 cubic feet and the weight is given as 5 pounds.
Specific Volume = 100 cubic feet / 5 pounds
Simplifying the equation gives us
Specific Volume = 20 cubic feet/pound
Therefore, the specific volume of the gas is 20ft³/lb. So, the correct answer is 20ft³/lb.
To find the specific volume of a gas, you need to divide the volume of the gas by its weight. The specific volume is a measure of how much space a unit weight (mass) of the substance occupies.
In this case, the gas has a weight of 5 pounds and a volume of 100 cubic feet. To find the specific volume, divide the volume (100 cubic feet) by the weight (5 pounds):
Specific volume = Volume / Weight = 100 ft³ / 5 lb
Simplifying the expression gives:
Specific volume = 20 ft³/lb
Therefore, the specific volume of the gas is 20 ft³/lb. So the correct answer is option C: 20ft³/lb.
specific volume is volume/mass (or weight)
so, just look at the units, and you have
100ft^3/5lb = ?
