Explanation:
Answer:
V₂ = 1.32 L
Explanation:
Given data:
Initial volume = 1.25 L
Initial pressure = 0.865 atm
Final volume = ?
Final pressure = 0.820 atm
Solution:
The given problem will be solved through the Boyle'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
0.865 atm × 1.25 L = 0.820 atm × V₂
V₂ = 1.08 atm. L/ 0.820 atm
V₂ = 1.32 L
Answer:
hydrogen bond
Explanation:
The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond. This bond is very weak.
<u>Answer:</u>
Comparing and contrasting embryos of different species is called Comparative embryology.
<u>Explanation:</u>
It is the branch of embryology where embryos of different specie are compared to find out that how two special are evolutionary similar or different from each other. It also helps in the identification of organism's closest ancestor. For example: When Aristotle observed embryos of different animal specie, he described that egg laying (oviparous) organisms are different from birth giving (viviparous) organisms. This has a connection with organism's developmental pattern which tell that both organisms have different or common ancestry.
Hope it helps!
