Karen measures the volume of gas at 200 K and 100 kPa. To correct her measurement to standard temperature and pressure (STP), wh
at must she do? A. make a volume correction based on a higher temperature of 273 K
B. make a volume correction based on a higher pressure to 200 kPa
C. make a volume correction based on a lower temperature of 73 K
D. make a volume correction based on a lower pressure of 50 kPa
I believe the correct answer from the choices listed above is option A. To correct her measurement to standard temperature and pressure (STP), she should <span>make a volume correction based on a higher temperature of 273 K. Hope this answers the question. Have a nice day.</span>
At STP (standard temperature and pressure), the temperature is 273 K and pressure is 1 atm or 101 KPa.
Karen measures the volume of gas at 200 K and 100 KPa.
From this we conclude that the pressure of the gas are approximately equal. So, to correct her measurement to standard temperature and pressure (STP), she should make a volume correction based on a higher temperature of 273K.
Hence, the correct option is, (A) make a volume correction based on a higher temperature of 273 K
The answer is 32.43 because when you round the number next to the hunthers place (witch in this problem would be the 1) has to be 5 or hight to raise the number to the left of it and if it is lower you just take the two number and that is your answer.
