A container containing 5.00 L of a gas is collected at 100 K and then allowed to expand to 20.0 L. What must the new temperature be in order to maintain the same pressure?
400 Kelvin (K).
We are given the initial volume and initial temperature (in Kelvins, so no need to convert from Celsius to Kelvin). We are also given the final volume.
In short, we have:
We have 3 of the 4 variables, and if we fill those in, we have...
Using the algebra skill of cross multiplying, we can get...
Dividing both sides by 5.00 to isolate the
It is 400. due to the significant figure rule.
