Definition
Define the term density
the mass per unit volume of a subtance
which state of matter is the densest?
Solid
What is the formula for calculating density using the mass and volume of an object
density = mass/volume
What is the unit of measurement of mass
kilograms or grams
Solid to liquid
Melting
the amount of matter a substance have
Which state of matter is the least dense?
gas
Calculate the density of an object when the mass is 25kg and the field volume is 10m3
2.5kg/m3
What is the unit of measurement of volume
Liquid to gas
Define volume
The amount of space an object takes up
How are the particles arranged in solid?
tightly packed

40cm3
How do you convert from centimetres to meters?
divide by a hundred
gas to liquid
condensing
Instrument used to measure mass
balance (not scale)
How do the particles in a solid move?
Vibrate in fixed position
