Answer:
-152.92°C
Explanation:
Initial volume = 0.750 mL
Initial temperature = -32.7 °C (-32.7 + 273.15 K = 240.45 k)
Final temperature = ?
Final volume = 0.750 mL / 2= 0.375 mL
Solution:
The given problem will be solve through the Charles Law.
Mathematical expression:
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
T₂ = T₁V₂ / V₁
T₂ = 240.45 k × 0.375 mL / 0.750 mL
T₂ = 90.17 mL.K / 0.750 mL
T₂ = 120.23 K
Temperature in celsius:
120.23 K - 273.15 = -152.92°C
Answer:
Notice that the photosphere actually has a temperature quite close, or even a bit colder, than the Earth's core! However, outside the photosphere there is the Sun's corona, which can reach temperatures as high as 17,000,000 K; this is hotter than the center of the Sun, and is the hottest place in the solar system!
The number of mole of the gas present in the sample which occupies a volume of 350 mL at 25 °C and 1 atm is 0.0143 mole
From the question given above, the following data were obtained:
Volume (V) = 350 mL = 350 / 1000 = 0.35 L
Temperature (T) = 25 °C = 25 + 273 = 298 K
Pressure (P) = 1 atm
Gas constant (R) = 0.0821 atm.L/Kmol
<h3>Number of mole (n) =? </h3>
With the application of the ideal gas equation, the number of mole of the gas present in the sample can be obtained as follow:
<h3>PV = nRT </h3>
1 × 0.35 = n × 0.0821 × 298
0.35 = n × 24.4658
Divide both side by 24.4658
n = 0.35 / 24.4658
<h3>n = 0.0143 mole </h3>
Therefore, the number of mole of the gas present in the sample is 0.0143 mole
