In the meantime, we have provided a simple overview:

​

Particle model:

Dalton- atoms= small indestructible spheres

Thompson- positive sphere with electrons embedded in it.

Rutherford- Small nucleus of positive charge surrounded by cloud of electrons.

                      Derived from gold foil experiment.

​

Density = Mass/ volume. How tightly packed together molecules are in a substance

Specific heat capacity- amount of energy required to increase the temperature by 1 degree Celsius of 1kg of a substance

Specifc latent heat- amount of energy required to change the state of 1kg of a substance

​

Pressure - force/area   --in gases, frequency of collisions with surface

Pressure is inversely proportional to volume 

Pressure is proportional to temperature.

Liquid pressure- density of liquid and depth under liquid determine pressure as greater force is being                                  exerted over same area.
