Density (T5)

Question 1

The density of n object is defined by what equation?

Answer 1

p = m / v

p = density in kg/m3

m = mass in kg

V = volume in m3

Question 2

Density is a measure of..

Answer 2

How much mass there is in one cubic metre of a particular material or object.

How tightly placed the particles are.

Question 3

What will making an object hollow do with regards to its density?

Answer 3

Its density will be less than it would be compared to a solid lump of the same material.

Question 4

Why does almost every metal float in Mercury?

Answer 4

Because it is so dense.

Question 5

How is the density of steel ships manipulated so they float on water?

Answer 5

Their hollowed out shape lowers their density enough to float on water.
