An arctic weather balloon is filled with 22.6L of helium gas inside a prep shed. The temperature inside the shed is 7°C. The bal
Liono4ka [1.6K]

Answer : The new volume of the balloon is, 22.4 L

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T

or,

\frac{V_1}{V_2}=\frac{T_1}{T_2}

where,

V_1 = initial volume of gas = 22.6 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 7^oC=273+7=280K

T_2 = final temperature of gas = 5^oC=273+5=278K

Now put all the given values in the above formula, we get the final volume of the gas.

\frac{22.6L}{V_2}=\frac{280K}{278K}

V_2=22.4L

Therefore, the new volume of the balloon is, 22.4 L

If 45.0 liters of oxygen is measured at 24.0C, what would be its volume at standard temperature?
nika2105 [10]

The volume of the oxygen gas at standard temperature  is 41.36 liters.

The given parameters;

  • <em>initial volume of oxygen, V₁ = 45 L</em>
  • <em>temperature of oxygen, T₁ = 24 ⁰C = 297 K</em>
  • <em>standard temperature, T₂ = 0 ⁰C = 273 K</em>

<em />

The volume of the oxygen gas at standard temperature is determined by applying Charles law as shown below;

\frac{V_1}{T_1} = \frac{V_2}{T_2} \\\\V_2 = \frac{V_1 T_2}{T_1} \\\\V_2 = \frac{45 \times 273}{297} \\\\V_2 = 41.36 \ L

Thus, the volume of the oxygen gas at standard temperature  is 41.36 L.
