Question

1. Suppose you have a piece each of granite, pumic, and marble. Predict which of the three would
not sink when put in a bucket of water. Give one reason to support your answer
​

Answer 1

Answer:

Because they are little bit lite In the bucket wrong or right

Answer 2

I support pumic because its density or weight is less so, that it will easily float on the water.

• The density ( more precisely, the volumetric mass viscosity; also known as specific mass), of a substance, is its mass per unit volume.
• The symbol most frequently used for viscosity is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.
• Mathematically, viscosity is defined as mass divided by volume.
• so, the density or weight of pumic is less.
