<h3>
Answer:</h3>
The equation is; P₁V₁/T₁ = P₂V₂/T₂
<h3>
Explanation:</h3>
Concept being tested: Combined gas law
We need to know the two gas laws that form the combined gas law
- The combined gas laws is derived from the Boyle's gas law and Charles's law.
- According to Boyle's law;
P₁V₁ = P₂V₂
- On the other hard, according to Charles's law;
V₁/T₁= V₂/T₂
- The combine gas laws combines both Boyle's law and Charles's law.
- According to the combined gas law, the volume of a fixed mass of a gas i inversely proportional to pressure and directly proportional to its absolute temperature.
- Therefore, combining both Boyle's law and Charles's law, we get;
P₁V₁/T₁ = P₂V₂/T₂
- Thus, based on Combined gas law, then
P₁V₁/T₁ = P₂V₂/T₂
Density of a liquid determines how it will layer (heaviest to lightest). If the liquid is least dense it will float to the bottom. Layers will remain separated because each liquid is actually floating on top of the more dense liquid beneath it.
Answer:
