The standard temperature and pressure for measuring the density of liquids is
- 15 degrees C and 760 mmHg.
- 0 degrees C and 760 mmHg.
- 4 degrees C and 760 mmHg.
Explanation
Liquid density is referenced to where water is at its maximum density, which occurs at 4 degrees C, together with standard atmospheric pressure of 760 mmHg. Using this datum gives water its reference density of 1000 kg/m3 against which other liquids are compared.
