P1.2 Flashcards
Density formula
Density = mass/volume
What is density?
Density tells you how much mass there is in a given volume
What state has the highest density
Solid
Why does solid have the highest density
Because there are more particles in a given volume than in a liquid or gas
Density does not only depend on the arrangement of particles but also….
…the mass of the particles
What is the units if density
Kg/cm3
What is the density of water (h20)
1000kg/cm3
What is the mass of 1 litre?
1kg
What is the volume of 1000 litres
1m3
What is the mass of 1 litre
1 kg
What is the mass of 1 ml
1 gram
What is the law of conservation of mass?
The mass of a substance stays the same throughout a physical change
What is heat?
- thermal energy
- amount of energy
What is temperature?
- the average kinetic energy of the particles
What is temperature measured in?
- Celsius
- kelvin
