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 two conditions that can limit the usefulness of the kinetic-molecular theory in describing gas behavior are "high pressure" and "low temperatures". At low temperatures or high pressures, real gases deviate significantly from ideal gas behavior.

Answer:
The answer to your question is letter A
Explanation:
Abundance Atomic mass
V-50 0.25% 49.947
V-51 99.750% 50.944
Formula
Average atomic mass = [V-50-Abundance x V-50-Atomic mass] +
[ V-51-Abundance x V-51-Atomic mass]
Substitution
Average atomic mass = [ 0.0025 x 49.947] + [0.9975 x 50.944]
= 0.125 + 50.817
Result
= 50.942 amu
