Question

What are values for standard temperature?
Check all that apply.

0°C

20°C

25°C

–273.15°C

273.15 K

Answer 1

Check: 0°C and 273.15 K.

Notes:
- 0°C and 273.15 K are equivalent and are the traditional "standard temperature" used for STP.
- 25°C (298.15 K) is commonly used as the standard thermochemical temperature (standard state), but it is not the STP standard temperature.
- 20°C is just a typical room temperature, not a defined standard.
- –273.15°C is absolute zero, not a standard temperature.
