Answer 1

Use a balance and record the data in kilograms.

Step-by-step explanation:

To answer this question, we need to know the difference between a balance and a scale.

A balance measures mass. In other words, a balance measures the amount of matter of an object. This measure is made by comparison with an object which mass is already known.

On the other hand, a scale measure weight, which is Netwons. Because a scale doesn't compare the unknown mass with another known mass. A scale measure the force due gravity exerted on an object.

Therefore, the right answer here is the first choice: Use a balance and record the data in kilograms.

Answer 2

Siobhan wants to measure the mass of a bag of flour. For measuring the mass of an object we can use balancing machine. The SI unit of mass is kilogram.

Thus, for measuring mass a balancing machine is used and the data should be recorded in kilograms.
