internal energy increases if
either the kinetic or potential energy of the particles increase
internal energy - if the temperature increases
the kinetic energy increases
internal energy - if the particles are pulled further apart
the potential energy increases
this happens during a change of state
internal energy - gas pressure increases if
temperature increases
particles have more kinetic energy so they move faster
more frequent collisions within the container
collisions have more force
latent heat - melting
temperature doesnt change
latent heat is the energy to change state
latent heat - boiling
temperature doesnt change
latent heat - solid
the temperature is rising
latent heat - liquid
the temperature is rising
latent heat - vaporisation
the temperature is rising
energy needed to melt 1kg of a substance
334,000 joules
energy needed to boil 1kg of a substance
227 kj
