Question

If a gas has a volume of 750 mL at 25°c, what would the volume of the gas be at 55°c?

Answer 1

Answer : The final volume of gas will be, 681.4 ml

Explanation :

Charles' Law : This law states that volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$     (At constant pressure and number of moles)

or,

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

where,

$V_1$ = initial volume of gas = 750 ml

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $25^oC=273+25=298K$

$T_2$ = final temperature of gas = $55^oC=273+55=328K$

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

$\frac{750ml}{298K}=\frac{V_2}{328K}$

$V_2=681.4ml$

Therefore, the final volume of gas will be, 681.4 ml

Answer 2

If a gas has a volume of 750 mL at 25°C, 681.4 mL is the volume of the gas be at 55°C.

What is the ideal gas equation?

Ideal gas equation will be represented as:

PV = nRT

From this equation it is clear that volume of gas is directly proportional to the temperature, and required equation for the question is:

V₁/T₁ = V₂/T₂, where

V₁ = initial volume of gas = 750 ml

T₁ = initial temperature of gas = 25°C = 298K

V₂ = final volume of gas = to find?

T₂ = final temperature of gas = 55°C = 328K

Putting all these values on the above equation and calculate for the value of V₂ as:

V₂ = (750×328) / 298 = 681.4 mL

Hence, 681.4 mL is the volume of gas.
