# A 5.00 L container contains #CH_4# at 35°C with a total pressure of 1.81 atm. What is the pressure of the gas when it expands to 25.0 L at 25°C?

It should be noted that I used absolute temperature because these issues always call for such measurements:

Use the combined gas law to find the final pressure (P2). The formula is P1 * V1 / T1 = P2 * V2 / T2. Plug in the given values: P2 = (1.81 * 5.00 * (25 + 273)) / (35 + 273 * 25.0). Calculate to find the pressure of the gas when it expands.

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.
