Explicación:

Paso 1: Información provista

Paso 2: Convertir 64 °C a Kelvin

Usaremos la siguiente fórmula.

K = °C + 273.15 = 64 °C + 273.15 = 337 K

Paso 3: Calcular V₂

Usaremos la ecuación combinada de los gases ideales.

P₁ × V₁ / T₁ = P₂ × V₂ / T₂

V₂ = P₁ × V₁ × T₂ / T₁ × P₂

V₂ = 96.4 kPa × 969 cm³ × 273.15 K / 337 K × 100 kPa = 757 cm³

Answer: 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.

Explanation:

Given: Mass = 20 g

Change in temperature = [tex]26^{o}C[/tex]

The standard value of specific heat of water is [tex]4.184 J/ g^{o}C[/tex]

Formula used to calculate the heat energy is as follows.

[tex]q = m \times C \times \Delta T[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat of substance

[tex]\Delta T[/tex] = change in temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times \Delta T\\= 20 g \times 4.184 J/g ^{o}C \times 26^{o}C\\= 2175.68 J[/tex]

Thus, we can conclude that 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.

Answer:

The pH of a solution with a Hydronium (H₃O⁺) ion concentration of 0.001 M is 3.

Explanation:

pH, short for Hydrogen Potential, is a measure used to establish the level of acidity or alkalinity of a solution.

pH indicates the amount of hydrogen ions present in a solution or substance. Mathematically the pH is the negative logarithm of the molar concentration of hydrogen ions or protons (H⁺) or hydronium ions (H₃O⁺).

pH= - log [H⁺]= - log [H₃O⁺]

The pH scale goes from 0 to 14. Values ​​less than 7 indicate the range of acidity and those greater than 7 indicate alkalinity or basicity. The value 7 is considered neutral.

In this case, [H₃O⁺]= 0.001 M.

Replacing in the definition of pH:

pH= - log (0.001 M)

Solving:

pH= 3

The pH of a solution with a Hydronium (H₃O⁺) ion concentration of 0.001 M is 3.

Answer:

5.12 m³

Explanation:

Using the combined gas law formula as follows:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (m³)

V2 = final volume (m³)

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question;

V1 = 5.0 m³

V2 = ?

P1 = 0.84 atm

P2 = 0.89 atm

T1 = 298 K

T2 = 323 K

Using

P1V1/T1 = P2V2/T2

0.84 × 5/298 = 0.89 × V2/323

4.2/298 = 0.89V2/323

Cross multiply

4.2 × 323 = 298 × 0.89V2

1356.6 = 265.22V2

V2 = 1356.6 ÷ 265.22

V2 = 5.12 m³

Answer:

The pressure of the gas at 323 degrees Celsius is 2 atm.

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.

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Where P = pressure, T = temperature, K = Constant

Having two different states, an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{1 atm}{298 K} =\frac{P2}{596 K}[/tex]

Solving:

[tex]P2=\frac{1 atm}{298 K}*596 K[/tex]

P2= 2 atm

The pressure of the gas at 323 degrees Celsius is 2 atm.
