Conservation of Energy (HSC SSCE Physics): Flashcards

Matter cannot enter/leave; energy can be transferred in/out

Neither energy nor matter can enter or leave

Energy cannot be created or destroyed in an isolated system

Energy added/removed during state change; temperature constant

Energy to change $1 ext{ kg}$ solid to liquid, no temp. change

Energy to change $1 ext{ kg}$ liquid to gas

$334 ext{ kJ} cdot ext{kg}^{-1}$

$2260 ext{ kJ} cdot ext{kg}^{-1}$

$Q = mL$

Remains constant even though energy is added or removed
