Question

3. Which of the following device is commonly used to measure the volume of liquids such as petrol
or kerosene?
a. measuring cup b. spring balance
c. conical cans
d. cylindrical cans​

Answer 1

Answer:

hydrometer

Explanation:

Liquid volume is usually measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass or plastic tube sealed at one end, with a calibrated scale etched (or marked) on the outside wall

They are typically calibrated and graduated with one or more scales such as specific gravity. A hydrometer usually consists of a sealed hollow glass tube with a wider bottom portion for buoyancy, a ballast such as lead or mercury for stability, and a narrow stem with graduations for measuring.

Answer 2

Explanation:

A hydrometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy.
