Answer:
V₂ = 119.59 cm³
Explanation:
Given data:
Initial volume = 150 cm³
Initial temperature = 72°C
Final volume = ?
Final temperature = 2°C
Solution:
Initial temperature = 72°C (72 +273.15 K = 345.15 K)
Final temperature = 2°C (2 + 273.15 k = 275.15 K)
Solution:
According to the Charles Law.
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 = 150 cm³ × 275.15 K /345.15 K
V₂ = 41272.5 cm³.K / 298 K
V₂ = 119.59 cm³
Answer:
An emulsion is formed.
Explanation:
An association (emulsion) of two liquids is formed, in this case oil and vinegar, which when stirred, said mixture will separate.
The two molecules will only react if they have enough energy. By heating the mixture, you are raising the energy levels of the molecules involved in the reaction. Increasing temperature also means the molecules are moving around faster and will therefore "bump" into each other more often.
