Vapor Pressure 1atm = 760 mmHg = 101.3kPa B is a Gas B is Liquid Normal Boiling Point for B
Heating Melting Boiling E Heating Liquid Heating Gas Heating Solid
Heating PE increasing E KE increasing PE increasing
Potential Energy Activation Energy Activation Energy of Reverse H reaction PE of Products PE of reactants PE of activated complex, think of the big hill on the roller coaster!
Phase Diagram Triple Point Temperature Pressure Solid Liquid Gas 1atm Normal Boiling Point Normal Freezing Point
Phase Diagram (water) Triple Point Temperature Pressure Solid Liquid Gas 1atm Normal Boiling Point Normal Freezing Point Negative slope implies lower solid density (ice floats)

Gases, Liquids and Solids
States of Matter.
Ch. 8 - Solids, Liquids, & Gases II. Changes in State (p ) Phase Changes Heating Curves MATTER.
Phase Changes Matter can change from one form to another. As this occurs, energy also changes.

Clausius – Clapeyron Equation This equation is a relation between H vap and pressure at a certain Temperature.
Energy and Phases. Potential Energy - stored energy (stored in bonds, height) Kinetic Energy - energy of motion, associated with heat.
Unit 10 States of Matter and Gases. Phase Changes A phase change is a change in the state of matter During a phase change there is no change in temperature.
Phase Changes Chp 10. Phase Diagrams Phase diagram = relates physical states of matter (solid, liquid, gas) to temperature and pressure.
Phase Changes What did one water molecule say to another water molecule about vapor? Don’t worry it’s just a phase he’ll cool down.
Unit 4: Chemical Reactions
Aim: How to measure energy absorbed during a phase change
How many joules are needed to change 120.g of
Phase Changes Melting Vaporization Condensation Freezing Sublimation.
PHASE CHANGES Matter can change from one state to another. This is known as a Phase Change. All Phase Changes are Physical Changes… The Identity of the.
Heating and Cooling Curve. Heating Curve Is a graph of heat added versus temperature Is useful in describing the change in temperature and the amount.
Heating/Cooling Curve Melting (ice & water) ALL ice ALL Water Vaporizing (water & vapor) ALL Vapor.
