Answer:</h3>
Gas law : Boyle's law
New pressure: 66.24 atm
<h3>
Explanation:</h3>
Concept tested: Gas laws (Boyle's law)
<u>We are given,</u>
- Initial pressure, P₁ = 2.86 atm
- Initial volume, V₁ = 8472 mL
- New volume, V₂ IS 365.8 mL
We need to determine the new pressure, P₂
- According to Boyle's law , the volume of a fixed mass of a gas and the pressure are inversely proportional at constant temperature.
- That is,
- This means , PV = k (constant)
- Therefore; P₁V₁ = P₂V₂
- Rearranging the formula, we can get the new pressure, P₂
P₂ = P₁V₁ ÷ V₂
= (2.86 atm × 8472 mL) ÷ 365.8 mL
= 66.24 atm
Therefore, the new pressure is 66.24 atm
The answer is A hopefully it is ok ✅
Endothermic change hope this helps.
Atomic number is Z. Z=number of protons, so Z=11
Answer:
V₂ = 626.52 mL
Explanation:
Given data:
Initial volume = 268 mL
Initial temperature = 151 K
Final temperature = 353 K
Final volume = ?
Solution:
V₁ / T₁ = V₂ / T₂
V₂ = V₁ T₂/ T₁
V₂ = 268 mL× 353 K / 151 K
V₂ = 94604 mL.K / 151 K
V₂ = 626.52 mL
