At a fixed pressure, if the temperature is doubled, the volume of a gas will be

Scrat [10]

Answer:

Doubled.

Explanation:

The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:

V₁*T₂ = V₂*T₁

That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.

How many moles are in 25g of NaCI?

emmainna [20.7K]

Nacl = (. 23+35. 5)

= 58.5g

1 mol of Nacl = 58.5g

X mol Of Nacl = 25g

X Mol of Na Cl =25 ÷ 58.5

X mol of Nacl = 0.4 mol

An ideal diatomic gas starting at room temperature T1 = 300 K and atmospheric pressure p1 = 1.0 atm is compressed adiabatically

tangare [24]

Answer:

The final temperature of the given ideal diatomic gas: T₂ = 753.6 K

Explanation:

Given: Atmospheric pressure: P = 1.0 atm

Initial Volume: V₁ , Final Volume: V₂ = V₁ (1/10)

⇒ V₁ / V₂ = 10

Initial Temperature: T₁ = 300 K, Final temperature: T₂ = ? K

For a diatomic ideal gas: γ = 7/5

For an adiabatic process:

$V^{\gamma-1 }T = constant$

$V_{1}^{\gamma-1 }T_{1} = V_{2}^{\gamma-1 }T_{2}$

$\left [\frac{V_{1}}{V_{2}} \right ]^{\gamma-1 } = \frac{T_{2}}{T_{1}}$

$\left [10 \right ]^{\frac{7}{5}-1 } = \frac{T_{2}}{300 K}$

$\left [10 \right ]^{\frac{2}{5} } = \frac{T_{2}}{300 K}$

$2.512 = \frac{T_{2}}{300 K}$

$T_{2} = 753.6 K$

Therefore, the final temperature of the given ideal diatomic gas: T₂ = 753.6 K
