Lab 1.2 quiz - you can practice with this one and then check your answers   Lab 1.2 Quiz - The Key    Lab 2013 1.2 test 1

Correct your own lab 1.2 worksheet.  Do you need any extra help or more practice?  Find out.   Lab 1.2 worksheet - The Key

Help from Luetgens in lab one  I highly recomend that you use this resource.

Powerpoint  An overview of all four lab parts.  Another useful resource. 

 Solids, Liquids, and Gases Simulation.  Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

Pressure caused by collisions animation  You can adjust the temperature and watch the particles.

Evaporation and water molecules - several helpful animations (keep going watch several segments)

Condensation - several helpful animations(keep going watch several segments)

Evaporative Cooling.  Watch the faster particles escape and the collection of particles left behind in the the liquid.

Freezing - animations to show strucutre of ice and freezing

Melting and Other changes of states - again more good animations

Polar Water Molecules - same website as above - good series of animations

Surface Tension - more from the same website

 Lab 1.1  Models are constructed to describe the water molecules in solids, liquids and gases.  Polar covalent bonding and dipole-dipole attractions are introduced.  Enthalpy and entropy are introduced.

 

Lab 1.2  The heat of fusion of water is measured and calculated.  Accuracy, precions and exactness in measurements are introduced.  Energy transfers are described between system and surroundings.  Enthalpy and entropy models are applied.

 

Lab 1.3  Models of enthalpy and entropy are used to explain the observed boiling and condensation of water.  Vapor pressure is introduced to explain boiling.  The relationship between temperature and vapor pressure is explained using temperature and pressure models.  Equilibrium is introduced as vapor pressure equilibrium.

 

Lab 1.4  Chemical reactions are introduced in the electrolysis of water.  Nonpolar covalent bonding and induced dipole-induced dipole attractions are introduced.
