Using the ideal gas law ( PV = nRT ), where ( P ) is pressure, ( V ) is volume, ( n ) is the number of moles, ( R ) is the gas constant, and ( T ) is temperature, we can rearrange the equation to solve for temperature: ( T = \frac{{PV}}{{nR}} ). Since the volume and the number of moles remain constant, the new temperature (( T_{new} )) can be calculated using the initial pressure (( P_{initial} )) and the final pressure (( P_{final} )): [ T_{new} = \frac{{P_{final} \times T_{initial}}}{{P_{initial}}} ] [ T_{new} = \frac{{27 , Pa \times 450 , K}}{{18 , Pa}} ] [ T_{new} = \frac{{12150 , K \cdot Pa}}{{18 , Pa}} ] [ T_{new} = 675 , K ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
