Chapter 17 Flashcards
Heat of Transformation
The heat required for matter to change states
Heat of Fusion
The heat required for matter to change from solid to liquid
Heat of Vaporisation
The heat required for matter to change from liquid to gas
Heat of Sublimation
The heat required for matter to change from solid to gas
What two parameters make up a phase diagram?
Pressure and temperature
What are two types of thermal expansion?
Volume and linear expansion
What happens to the pressure when the temperature is increased, but volume is held constant?
Pressure will increase as the molecules have more energy and are bumping into each other more
What happens to the volume when the pressure is increased?
Volume decreases
In terms of kinetic energy in molecules, what relation does it have to temperature?
Temperature is a measure of their kinetic energy.
Ek = 1.5kT
