Answer:
V₂ = 123.6 L
Explanation:
According to Boyle's law pressure and volume of a gas are inversely related if amount and temperature are kept constant. For the initial and final states the gas law is given as,
P₁ V₁ = P₂ V₂ ----- (1)
Data Given;
P₁ = 103 kPa
V₁ = 30 L
P₂ = 25 kPa
V₂ = ?
Solution:
Solving equation 1 for V₂,
V₂ = P₁ V₁ / P₂
Putting values,
V₂ = (103 kPa × 30 L) ÷ 25 kPa
V₂ = 123.6 L
Result:
As the pressure is decreased from 103 kPa to 25 kPa, therefore, volume has increased from 30 L to 123.6 L.

Answer:
The answer to your question is: letter C
Explanation:
a. the sharing of electrons between a hydrogen atom and another atom. This description is not for hydrogen bonding, in hydrogen bonding atoms do not share electrons, to form this bond.
b. the electrostatic interaction between an atom that has lost an electron and an atom that has gained an electron. This definition is describing an ionic bonding, not a hydrogen bonding.
c. the interaction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. This is the right definition of hydrogen bonding, because is mentioning the interaction between a hydrogen and an electronegative atom.
Answer:
B
Explanation:
Biotic factors are alive. Some examples include plants, animals and fungi.
The “a” in front of abiotic will negate the meaning of the word. Therefore, abiotic means not living. Some examples are rocks, water and air.
So, we know that biotic factors are living, and abiotic factors are not living. Therefore, B is correct.
