Question

A student has two objects. Object 1 has a mass of 10 g and a volume of 5 cubic centimeters. Object 2 has a mass of 10 g and a volume of 20 cubic centimeters. If both objects are placed in water, which will float and why?

Answer 1

Answer:

Second object will float because its density less than 1

Explanation:

Object 1

Mass = 10 g

Volume = 5 cm3

Density = mass /volume

= 10g/ 5 cm3

Density = 2 g/cm3

Object 2

Mass = 10 g

Volume = 20 cm3

Density = mass /volume

Density = 10g/ 20 cm3

Density = 0.5 g/cm3

Density is less than 1 objects float in the water so object 2 is floats on water
