Answer:
Perfectly Specified
Explanation:
Pressure, P = 0.9 atm
Boiling point = T
Number of components C = 1
Number of phases P = 2
Using Gibbs phase rule as:
F = C - P + 2
F = 1 - 2 + 2 = 1
At Pressure = 0.9 atm, boiling point is T which means that the temperature is also fixed which is equal to 96.7 °C . The data taken from steam table.
In given problem, the pressure is fixed so temperature is also fixed.
The system is perfectly specified.
Answer:
first choice
Explanation:
energy is written on the left side is its absorbed
2 elements came together so bonds are formed.
Answer:
V₂ = 112.14 mL
Explanation:
Given data:
Initial volume = 500 mL
Initial pressure = 270 mmHg (270/760 =0.355 atm)
Initial temperature = 55 °C (55 +273 = 328 K)
Final temperature = 100°C (100+273 = 373 K)
Final volume = ?
Final pressure = 1.8 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 0.355 atm × 500mL × 373 K / 328 K × 1.8 atm
V₂ = 66207.5 atm .mL. K / 590.4 K.atm
V₂ = 112.14 mL
Under the same conditions of temperature and pressure, a liquid differs from a gas because the particles of the liquid a) are in constant straight-line
