Answer: The correct answer is 'temperature will get doubled that is option D.
Explanation:
Suppose the volume of the bubble is V, at temperature T and Pressure exerted by atmosphere P.
When bubble is blown with more air until the volume doubles the initial volume:
The new volume of the bubble = V'=2V
The new Temperature of the air inside the bubble will change to T'.
And the atmospheric Pressure remains same.
According Charles law:
(At constant Pressure)
So, this means that temperature will get 2 times the initial temperature of the gas.
Hence, the correct answer is 'temperature will get doubled that is option D.
Answer:
The answer to your question is : letter B. 0.25 atm
Explanation:
To solve this problem we need to use the combined gas law:
<u>P₁V₁</u> = <u>P₂V₂</u>
T₁ T₂
Data
P1 = 0.99 atm V1 = 2 l T1 = 273K
P2 = ? V2 = 4 l T2 = 137K
Now, the clear P2 from the equation and we get
P2 = P1V1T2 / T1V2
Substitution P2 = (2 x 0.99 x 137)/(273 x 4)
P2 = 271.26 / 1092
Result P2 = 0.248 atm ≈ 0.25 atm
It has a role as a fertilizer. It is a potassium salt and an inorganic chloride.
