Since you all have a free day tomorrow, I hope you will be studying for your Science test! ;)
Key terms to know
heat
temperature
mechanical mixture
solution
pure substance
homogeneous
heterogeneous
changes of state
freezing (solidification)
melting
evaporation
condensation
sublimation (solid to gas)
deposition (gas to solid)
Concepts to know
- The behaviour of particles in solids, liquids, and gases (e.g, particle attraction, spaces between particles, movement of particles, volume)
- Which changes of states require heat, which require cooling
- The difference between temperature and heat
The test is very easy if you study! Good luck!
