Chapter 5 - Pressure, Volume and Temperture Flashcards
1
Q
When compression is applied in a closed system:
A
Volume decreases - more liquids than gases, pressure increases - particles have more collisions, temperature increases - more collisions means more movement resulting in heat
2
Q
When compression in removed from a closed system:
A
Volume increases - much more gasses than liquids, pressure decreases - particles have less collisions, temperature decreases - less collisions means less movement resulting in less heat
3
