Question

How do scientists measure mass? How do scientists measure volume?

A) Scientists measure mass using a ruler; Scientists measure volume using a scale.
B) Scientists measure mass using a graduated cylinder; Scientists measure volume using a balance.
C) Scientists measure mass using a balance; Scientists measure volume using a graduated cylinder.
D) Scientists measure mass using a scale; Scientists measure volume using a ruler.

Answer 1

Scientists measure mass using a balance for precision and volume using a graduated cylinder, especially for liquids. The correct option, given the choices, is C.

Step-by-step explanation:

When scientists need to measure mass, they use a device called a balance or a scale. Balances are often preferred in the laboratory for their precision and are calibrated with a standard mass. As for measuring the volume of substances, scientists use a graduated cylinder for liquids, which allows for accurate measurement of their capacity. The volume of regular solids can be computed from their geometric parameters, such as length, width, and height.

In the context of the choices provided:

• A) Incorrect - Mass is not measured with a ruler; volume is not measured using a scale.
• B) Incorrect - Mass is not measured with a graduated cylinder; volume is not measured using a balance.
• C) Correct - Scientists measure mass using a balance; Scientists measure volume using a graduated cylinder.
• D) Incorrect - Mass is not measured using a ruler or scale for precision; volume is not measured using a ruler.
