Hi, so we are to select the temperature and pressure that corresponds to standard temperature and pressure or stp.
00:11
So what you have to remember is that the temperature at stp, i'm writing here first, the temperature at stp is equivalent to zero degrees celsius or in terms of kelvin, this is 273 .15 if you want to be exact or just 273 kelvin.
00:31
Okay, and then the pressure is 180 m.
00:36
And for other units, this could also be in terms of torr, that's 760 torr since 180 m is equivalent to 760 torr or 760 mmhg and other units that corresponds to 180 m.
00:55
And based on the given choices here, first one we have 298 kelvin and 180 m.
01:00
This contains correct value of pressure but the temperature is at 25 degrees celsius, 298 kelvin so this is wrong.
01:09
Second choice we have 273 kelvin, correct temperature but 1 pascal.
01:15
1 pascal is not equivalent to 180 m.
01:18
180 m is equivalent to 10325 pascal.
01:22
So the second choice is wrong.
01:24
And then third one we're given with a pair 373 kelvin and 760 torr...
