Energy Changing Processes
In this video Paul Andersen explains how energy can enter and leave a system. The amount of energy a substance can receive through heating or lose through cooling is measured using the specific heat capacity. Phase changing energy from...

Why Does Water Evaporate at Room Temperature?
Water evaporates at room temperature because the molecules at the top of the liquid have less intermolecular attraction than those within the bulk. When the top layer is exposed to sunlight, some molecules gain enough kinetic energy to...

Heat of Vaporization
This program begins by defining heat of vaporization is the amount of heat that must be added or given off to vaporize one gram or kilogram of a substance and is expressed as J/g or J/kg. Through real, live footage and animation,...

Practice Problem: Calculating Free Energy Change
We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

Practice Problem: Enthalpy of Vaporization
Can we do stoichiometry regarding phase changes? Sure! If we know how many moles of a substance we have, and the energy associated with each mole of that substance undergoing a particular phase change, we can get the energy associated...

Changes of States of Matter
While scientists debate if there are five or seven different states of matter, this video introduces the most common three. It explains the properties of each, kinetic theory, and the changes that occur due to temperature fluctuation.
