1
Q
What is density?
A
Density tell you how much mass there is in a certain volume
2
Q
How do you calculate density?
A
Density (kg/m^3) =
mass(kg) ———————— volume(m^3)
3
Q
Why is a solid denser than a liquid or gas?
A
There are more particles in the same volume of a substance in the solid state than in the liquid or gas state
4
Q
What density depend on?
A
Particle arrangement
Mass of particles
5
Q
What is conservation of mass?
A
Particles do not appear or disappear
When you melt, freeze, condense evaporate or sublimate a substance the mass stays the same
