The First Law of Thermodynamics: Internal Energy, Heat, and Work
In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in...

Converting Between Temperature Scales (Celsius, Fahrenheit, and Kelvin)
If you're American, you're familiar with the Fahrenheit scale, so 30 degrees is cold and 100 degrees is hot. But in the rest of the world, nobody uses this scale! They use Celsius, and to them, 30 is pretty darn hot. Furthermore,...

Calculating Ion Concentrations in Solution
We know that concentration is typically expressed with molarity, which is moles per liter. But how do we know how many moles of solute are present in solution when an ionic solid dissolves in water? It's not so simple because these will...

Calculating Percent Error
Sometimes we take measurements, and sometimes we're off by a little bit. How far off? Does it make sense to just use a number? Shouldn't we use something that tells us how far off we are relative to the true value? Yes we should, hence,...

Expressing Concentration by Mass Percent
We know how to express solution concentration in terms of molarity and molality, but the common public also needs to communicate concentration for certain reasons, and they don't really know about moles and things like that. What do they...
