<span>How iron can be more dense as a feather yet more feathers can weigh more is because density and weight are two completely different things. No matter how many feathers there are it's density never changes, it's weight is able to change but not density. Therefore the density of iron is higher no matter what but may weigh less than a group of feathers.</span>
Answer:
1.8 L
Explanation:
Given data:
Initial volume of gas = 4.2 L
Initial pressure of gas = 101 kpa
Final volume of gas = ?
Final pressure of gas = 235 kpa
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
101 kpa × 4.2 L = 235 kpa × V₂
V₂ = 424.2 kpa . L/ 235 kpa
V₂ = 1.8 L
So when pressure is increased the volume of gas becomes 1,8 L.
Iron is a element while steel is an annoy.
