Chapter question
How can adding or removing energy change matter?
Units in this chapter
- Unit 2.1 · States of Matter & Phase Changes
I can describe how particle arrangement and motion differ in solids, liquids, and gases.
- Unit 2.2 · Temperature & Thermal Energy
I can distinguish temperature from the total thermal energy of a sample.
- Unit 2.3 · Gas Particles, Diffusion & Pressure
I can explain diffusion and gas pressure with particle motion and collisions.
- Unit 2.4 · Evaporation, Condensation & a Wet Cold Cup
I can account for water during evaporation and condensation using a boundary and a particle model.
- Unit 2.5 · Heating Curves & Energy During Phase Change
I can interpret a heating graph’s axes, rising intervals and phase-change plateau.
