Question

You are given 2 samples is a pure copper, sample A with a mass of 20 g and sample B with a mass of 100 g. Compare the two in terms of volume.(20, 26)

Answer 1

To compare volumes of two pure copper samples, we calculate their volumes by dividing their masses by the density of copper (8.96 g/cm³). Sample A with 20 g has a volume of approximately 2.23 cm³, and sample B with 100 g has a volume of approximately 11.16 cm³, thus sample B has a larger volume.

Step-by-step explanation:

To compare the volumes of two samples of pure copper, sample A with a mass of 20 g and sample B with a mass of 100 g, we need to use the density of pure copper, which is 8.96 g/cm³ (using a commonly accepted value for the density of copper).

1. Calculate the volume of the first sample (Sample A): Volume = Mass / Density. Volume of Sample A = 20 g / 8.96 g/cm³ = 2.23 cm³ (approximately).
2. Calculate the volume of the second sample (Sample B): Volume of Sample B = 100 g / 8.96 g/cm³ = 11.16 cm³ (approximately).

Therefore, sample B has a greater volume than sample A. This is expected since sample B has a larger mass and, assuming the density is constant, its volume should be proportionally larger.
