Question

Which equation will you use to calculate the volume of a 5.00 liter sample of air at 50°C when it is warmed to 100°C at constant pressure?

Answer 1

I believe it's a proportion of volume over temperature = volume and temperature. cross multiply and divide and see what u get. if it looks right go fro it if not try something else. I hope this helps!

Answer 2

Answer : The final volume of gas will be, 5.77 liters

Explanation :

Charles' Law : It is defined as the volume of the 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 = 5.00 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $50^oC=273+50=323K$

$T_2$ = final temperature of gas = $100^oC=273+100=373K$

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

$\frac{5L}{V_2}=\frac{323K}{373K}$

$V_2=5.77L$

Therefore, the final volume of gas will be, 5.77 liters
