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.

- A star is five times as luminous as the Sun and has a surface temperature of 98,000 K. What is its radius, compared to that of the Sun?
- A #3 L# container holds #9 # mol and #12 # mol of gasses A and B, respectively. Groups of three of molecules of gas B bind to two molecules of gas A and the reaction changes the temperature from #160# #K# to #360# #K#. How much does the pressure change?
- A #3 L# container holds #30 # mol and #15 # mol of gasses A and B, respectively. Groups of three of molecules of gas B bind to five molecules of gas A and the reaction changes the temperature from #320^oK# to #480^oK#. How much does the pressure change?
