Thermal Physics Flashcards
Triple Point
one specific temp and pressure where the three phases of matter of that substance can exist in thermal equilibrium
thermal equilibrium
when there is no net transfer of thermal energy between phases
zeroth law of thermodynamics
if 2 objects are in thermal equilibrium with a third, then all three are in thermal equilibrium with each other
atomic arrangement in solids
atoms or molecules arranged regularly and packed closely together
ke in liquids compared to solids
more ke in liquids than in solids
density equation
mass/volume
internal energy
the sum of the randomly distributed kinetic and potential energies of atoms or molecules within the substance.
what happens to the internal energy as temperature increases
ke increases
what happens to the energy during state change
ke stays the same but pe increases
shc
the energy required per unit mass to change the temperature by 1 kelvin
how to be accurate in shc experiment
- stir liquid and insulate container
slh
energy required to change the phase per unit mass at a constant temp
fusion
solid to liquid
vaporisation
liquid to gas
