A gas has a temperature of 273.15 K and a pressure of 101.325 kPa. What can be concluded about the gas?
Answer
A
It has reached standard temperature and pressure.
B
The pressure needs to be increased to reach the standard pressure.
C
The temperature needs to be increased to reach the standard temperature.
D
Both the temperature and pressure need to be lowered to reach STP.
Explanation
Standard temperature and pressure (STP) is 273.15 K and 101.325 kPa. The gas is already at both of these values, so it has reached standard temperature and pressure.
