Some physical properties change, but the substance keeps its identity.
When dealing with these kind of questions, understand that the keyword here is physical change. Thus, all options that says no physical properties change are WRONG. So this leaves us with only 2 answers left. However, this is a physical change, no chemical change. Thus, the substance will keep its identity and not change.
Answer:
759779.6 torr
Explanation:
Initial volume, V₁ = 4001 mL
Final volume, V₂ = 3002 mL
Initial pressure, P₁ = 750.1 atm
We need to find the final pressure at a constant temperature. Let it be P₂. 
We know that,
1 atm = 760 torr
So,
999.71 atm = 759779.6 torr
Hence, there will be 759779.6 torr pressure.
Answer:
Is there supposed to be a picture??
Explanation:
Answer:
P₂ = 220.56KPa
Explanation:
Boyles Law P ∝ 1/V => Inverse relationship => Decreasing Volume => Increasing Pressure.
P₁ = 198 KPa P₂ = ?
V₁ = 15.35 Liters V₂ = 13.78 Liters
P₁V₁ = P₂V₂ => P₂ = P₁(V₁/V₂) = 198KPa(15.35 L/ 13.78L) = 220.6KPa
