... Measuring ΔH Using a Coffee-Cup Calorimeter When a student mixes 50 mL of 1.0 M HCl and 50 mL of 1.0 M NaOH in a coffee-cup calorimeter, the temperature of the resultant solution increases from 21.0 ˚C to 27.5 ˚C. Calculate the enthalpy change for the reaction in kJ/mol HCl, assuming that the calori ...

... These equations underlie a physical discrepancy with this problem. The kinematic equations above rely on an ideal system in which all of the potential energy of the falling object is converted into kinematic energy. There are corrections to these equations in the case where radiation is significant ...

... We’ve talked about kinetic energy, which is energy of motion - if something isn’t moving, it has no kinetic energy. We defined energy as the ability to do work and saw that we could change the kinetic energy of an object by doing work on it. Potential energy can be thought of as energy of position, ...
