At 303 K, the volume of a gas is 30.0 ml. At constant pressure, what is the new
1 answer:
Answer:
V₂ = 28 mL
Explanation:
Given data:
Initial temperature = 303 K
Initial volume = 30.0 mL
Final temperature = 283 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 30.0 mL × 283 K /303 K
V₂ = 8490 mL.K / 303 K
V₂ = 28 mL
