Question

The standard temperature and pressure for measuring the density of liquids is.
Option A. 15 °C and 760 mmHg.
Option B. 0 °C and 760 mmHg.
Option C. 4 °C and 760 mmHg.

Answer 1

Option $C.\ 4\degree C \ \ \ and \ \ 760mm \ Hg$

Explanation:

Since water is most dense at 4 °C $(1000\frac{kg}{m^3})$ , this is used as the standard temperature. When working out specific gravity, the fluid must also be 4 °C.
