How to use a Calculator with Equations in Chemistry
This video will walk you though how to plug numbers into your calculator in chemistry class when you have an equation. You can use this logic for all equations in chemistry like density, specific heat, the gas laws... etc.
Ping Pong Ball - Gas Laws
Watch a ping pong ball have it's dent removed when placed into boiling water. The temperature increases therefore the pressure of the gas inside of the ball increases - the volume of the ball remains the same. Therefore the pressure pushes the dent out of the ball.
102 Dimensional Analysis, Density, Significant Figures Review
This is a review of dimensional analysis (the metric & English system), significant figures, density, and kelvin temperature conversions. It is recommended that you work the review sheet first then check your answers and then scroll to the question number that you need help with in the video. You have to practice in chemistry, working the review sheet first will help you to identify what concepts you need to focus on the most while studying.
110 Thermochemistry Review
This is a review of thermochemistry. Specific heat, enthalpy changes, endothermic and exothermic reactions, and Hess's law.
103 Matter, Physical/Chemical Changes, the Atom, Isotopes Review
This is a review of chapters 3 & 4. The topics covered include physical and chemical changes, physical and chemical properties, mixtures, separation of mixtures, pure substances, elements, compounds, isotopes and Rutherford model of the atom. It is recommended that you work the review sheet first then check your answers and then scroll to the question number that you need help with in the video.
