Unheated
kumpel [21]

Explanation:

Using the Combined Gas Law, which is:

\frac{P_1V_1}{T_1}  =\frac{P_2V_2}{T_2}

<em>(With </em>P_1,V_1,T_1 <em>being initial pressure, volume and temperature; and</em>

<em />P_2,V_2,T_2<em> being the new values)</em>

<em />

We can move the units around in order to solve for P_2, which would look like this:

P_{2} =\frac{P_1V_1T_2}{V_2T_1}

Then we convert the Celsius temperature to Kelvin:

25 °C = 289 K

100 °C = 373 K

And now, we plug in all of the values and solve, with volume remaining as a constant:

P_{2} =\frac{(1.00 atm) (20.0 L) (373 K)}{(20.0 L) (298 K)} =

1.25 atm <em>or </em>127 kPa
