Assume gas behaves as an ideal gas so we can relate the pressure, volume, and temperature of a fixed amount of gas at different conditions using the combined gas law, where p1 is the pressure, where p is the pressure, v is the volume, and t is the temperature in kelvin.

In this problem, a 26 .4 -liter sample of nitrogen gas at 7 .5 atmosphere and temperature of 24 degrees celsius is simultaneously expanded to a volume of 58 .4 liters and at heat.
00:30
Heated to a temperature of 35 degrees celsius.
00:33
We want to find the new pressure of the gas.
00:36
So that's p2 in this case.
00:38
So rearranging the equation that we have above for the combined gas, not to solve for p2, we get b1 v1 times t2 divided by t1 times b2.
00:51
So we note that temperature needs to be in kelvin.
00:54
So we'll convert 24 degrees celsius to kelvin by adding 273 to it.
00:59
Doing that gives us 297.
01:02
Also for 35 degrees celsius we have 35 plus 273...
