Answers
Answer:
6.75 sym.
Explanation:
Boyle's Law: The pressure of a gas in an enclosed container with a flexible volume is inversely proportional to the volume occupied by the gas.
Empirically => P ∝ 1/V => P = k(1/V) => k = P·V
For any conditions of Pressure & Volume, Pressure x Volume is a constant.
Therefore, k₁ = k₂ => P₁V₁ = P₂V₂ => V₂ = P₁V₁ / V₂
=> V₂ = (3atm)(0.450L)/(0.200L) = 6.75 atm.
Gas is confined in a metal tank in the figure. At 20.20°C, the gas exerts a pressure of 8.532 atm.
After heating the tank, the pressure of the gas increases to 10.406 atm. What is the temperature of
the heated gas?
Answers
Answer:
The temperature of the heated gas is 357.6 K (or 84.6 C)
Explanation:
Gay Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
So, this law indicates that the quotient between pressure and temperature is constant:
[tex]\frac{P}{T} =k[/tex]
You want to study two different states, an initial state 1 and a final state 2. Then it is true:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 8.532 atmT1= 20.20 C= 293.2 K (being 0 C= 273 K)P2= 10.406 atmT2= ?Replacing:
[tex]\frac{8.532 atm}{293.2 K} =\frac{10.406 atm}{T2}[/tex]
Solving:
[tex]T2*\frac{8.532 atm}{293.2 K} =10.406 atm[/tex]
[tex]T2=10.406 atm*\frac{293.2 K}{8.532 atm}[/tex]
T2= 357.6 K
The temperature of the heated gas is 357.6 K (or 84.6 C)
The new temperature of the heated gas when the pressure increase to 10.406 atm is 84.60 °C
Data obtained from the question Initial temperature (T₁) = 20.20°C = 20.20 + 273 = 293.20 KInitial pressure (P₁) = 8.532 atm Volume = constant New pressure (P₂) = 10.406 atmNew temperature (T₂) =? How to determine the new temperatureThe new temperature of the gas can be obtained by using the combined gas equation as illustrated below:
P₁V₁ / T₁ = P₂V₂ / T₂
Since the volume is constant, we have:
P₁ / T₁ = P₂ / T₂
8.532 / 293.20 = 10.406 / T₂
Cross multiply
8.532 × T₂ = 293.20 × 10.406
Divide both side by 8.532
T₂ = (293.20 × 10.406) / 8.532
T₂ = 357.6 K
Subtract 273 from 357.6 K to express in degree celsius
T₂ = 357.6 – 273
T₂ = 84.60 °C

O Boyle's Law
O Charles' Law
O Gay-Lussac's Law
Avogadro's Law
Answers
Answer:
Avogadro's Law; 15.1L
Explanation:
Boyle's Law- Pressure and volume are inversely related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.
Charle's Law- Gas expands/increases in volume when temperature increases, so they are proportional. We see this in the formula [tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex].
Guy-Lussac's Law- As temperature increases, pressure increases, so they are proportional. We see this in the formula [tex]\frac{P1}{T1} = \frac{P2}{T2}[/tex].
Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula [tex]\frac{V1}{n1} = \frac{V2}{n2}[/tex].
Plugging in the values based on Avogadro's Law, we'll have:
[tex]\frac{36.5}{2.9} = \frac{V2}{1.2}[/tex]
12.6 = [tex]\frac{V2}{1.2}[/tex]
12.6 x 1.2 = V2
15.1L =V2
