The Particle Model of Matter Flashcards
Density equation
Mass(kg)/volume(m³)
Internal Energy
Energy stored in a system by the particles that make up the system
How does heating change the energy stored in system
Increases the energy of the particles making up the system
Heating increases temperature
Atoms/molecules move faster and the kinetic energy of the atoms increases
Heating causes a change in state
e.g. when a solid changes to a liquid hbjdsbhzf,cdsj
Heat is
internal energy measured in J
Temperature is
dependent on the speed of particle movement, measured in degrees C
Specific heat capacity definition
The heat energy required to change the temperature of 1kg of a substance by 1 degrees C with NO STATE CHANGE
Specific heat capacity formula
Change in Energy = mass x specific heat capacity x temp change
