Thurs-Day 1
Physics - we discussed electric fields, and did some quantitative problems relating electric field strength to the force on a given charge.
We then went through six classic cases of representing the electric field lines/arrows/vectors for a given set of charges.
We then discussed the meaning of volts, as the work done in moving a quantity of charge. The work is equal to the change in potential energy of the charge and the quantity of charge is given in Coulombs.
We will use the term "potential difference" for the number of Volts, and relate that to the work produced by a given amount of charge.
We started an electrostatics lab during which you observed charging via conduction, and then via induction.
AP Chem - we rearranged the colligative property formula for freezing point depression and boiling point elevation. We will rearrange the osmotic pressure formula tomorrow, and then finish up the unit with Raoult's Law and any questions that you have from the break assignment.
