Density (T5) Flashcards
1
Q
The density of n object is defined by what equation?
A
p = m / v
p = density in kg/m3
m = mass in kg
V = volume in m3
2
Q
Density is a measure of..
A
How much mass there is in one cubic metre of a particular material or object.
How tightly placed the particles are.
3
Q
What will making an object hollow do with regards to its density?
A
Its density will be less than it would be compared to a solid lump of the same material.
4
Q
Why does almost every metal float in Mercury?
A
Because it is so dense.
5
Q
How is the density of steel ships manipulated so they float on water?
A
Their hollowed out shape lowers their density enough to float on water.
