b. salinity All three can be used to measure the amount of salinity is a liquid sample. Hydrometers and refractometers can also be used to measure other concentrations such as sugar content.
The American Petroleum Institute (API) scale on hydrometers is a measurement system used to determine the density of petroleum liquids like gasoline and diesel. It provides a standardized way to measure the specific gravity of these liquids, which is important for assessing their quality and purity. The API scale is commonly used in the oil and gas industry for fuel testing and analysis.
Two metric units that can measure the length of a bus are meters and centimeters.
To measure temperature, scientists use:KelvinCelsiusFahrenheit.
