You have two samples of the same gas in the same size container, at the same pressure. The temperature in the first container is -23°C and the temperature in the second container is 227°C. What is the ratio of the number of moles of gas in the first container compared to that in the second container?


the answer is 2:1

but WHY!!!

Don't know how to start or do problem:(

With gas problems, always think in terms of Kelvin temperatures.

-23 + 273 = 250 K
227 + 273 = 500 K

The second container is twice as hot as the first container, but it has the same pressure. The only way this could happen would be if it had half as many gas particles as the first container. That's where the 2:1 ratio comes from.
