Standard Temperature and Pressure
Multiple Choice
Which of the following best describes the conditions represented by the abbreviation STP in chemistry?
A
Temperature of 273 K and pressure of 2 atm
B
Temperature of 0°C and pressure of 760 mmHg
C
Temperature of 25°C and pressure of 1 atm
D
Temperature of 0°C and pressure of 1 atm
Verified step by step guidance1
Understand that STP stands for Standard Temperature and Pressure, which is a set of conditions commonly used in chemistry to describe gases.
Recall the standard temperature in STP is 0°C, which is equivalent to 273 K. This is a key reference point for many gas law calculations.
Recall the standard pressure in STP is 1 atm, which is equivalent to 760 mmHg or 101.3 kPa. This pressure is used as a baseline for comparing gas behaviors.
Compare the given options to these standard values: temperature of 0°C (273 K) and pressure of 1 atm (760 mmHg).
Identify that the option stating 'Temperature of 0°C and pressure of 760 mmHg' correctly matches the standard conditions for STP.
