Question

#1: Karen measures the volume of a gas at 200 K and 100 kPa. To correct her measurement to standard temperature and pressure (STP), what must she do?

A. make a volume correction based on a higher pressure of 200 kPa

B. make a volume correction based on a higher temperature of 273 K

C. make a volume correction based on a lower pressure of 50 kPa

D. make a volume correction based on a lower temperature of 73 K

**my answer: B

is that right?,

Answer 1

To correct her measurement to standard temperature and pressure (STP), she must make a volume correction based on a higher temperature of 273 K. The answer is letter B. This is in order to correct the temperature and pressure because correcting the volume will indicate that the temperature and pressure will result to the opposite result of the volume. This is because volume is indirectly proportional with pressure and temperature.
