Question

In the PhET simulation window, click the radio button labeled Mystery in the Blocks menu on the right-hand side of the screen. Using the scale and water tank, determine the mass of each block using the scale and the volume of each block by submerging it in water. Use these values to calculate the density. Rank the mystery blocks in order from least dense to most dense. Rank from least dense to most dense. To rank items as equivalent, overlap them.
Tank A 103.38 L, B 100.64 L, C 104.08 L, D 103.10 L, E 101.00 L

Scale A 65.14 kg, B 0.64 kg, C 4.08 kg, D 3.10 kg, E 3.53 kg

Answer 1

Answer:

B, D, E, C, A

Explanation:

We have 5 blocks with their respective masses and volumes.

Block            Mass            Volume

  A                65.14 kg       103.38 L

  B                0.64 kg         100.64 L

  C                4.08 kg         104.08 L

  D                3.10 kg          103.10 L

  E                 3.53 kg         101.00 L

The density (ρ) is an intensive property resulting from dividing the mass (m) by the volume (V), that is, ρ = m / V

ρA = 65.14 kg / 103.38 L = 0.6301 kg/L

ρB = 0.64 kg / 100.64 L = 0.0064 kg/L

ρC = 4.08 kg / 104.08 L = 0.0392 kg/L

ρD = 3.10 kg / 103.10 L = 0.0301 kg/L

ρE = 3.53 kg / 101.00 L = 0.0350 kg/L

The order from least dense to most dense is B, D, E, C, A
