Answer:
Measure the diameter of the circle using Ruler A and Ruler B.
Given that the actual diameter of the circle is 2.264 cm, classify the following statements that describe the diameter measurement of the circle according to the ruler.
Drag the appropriate items to their respective bins.
They are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature.
