Look up the freezing point of the liquid (solvent) for which you are calculating the new freezing point. You can find the freezing point of any chemical on the material safety data sheet that accompanies it. For example, water has a freezing point of 0 degrees Celsius. Step 2 Calculate th...
Lowering the freezing point of water is easy. All you have to do is add salt, sugar or any other solute. Going in the opposite direction and raising the freezing temperature of water is not nearly as easy. In fact, some scientists doubt that it even be done. However, even though it m...
Freezing point depression is one of thecolligative properties of matter, which means it is affected by the number of particles, not the chemical identity of the particles or their mass. When a solute is added to a solvent, its freezing point is lowered from the original value of the pure s...
Many commercial thermometers contain alcohol because alcohol has a low freezing point. As the temperature of the alcohol increases, it expands and causes the level within the thermometer to rise. The level of the alcohol corresponds to the printed lines/numbers on a thermometer indicating the temper...
Innovative chefs use flash freezing to create fluid-filled fare. It's simple: Expose food to extremely low temperatures, and it will remain frozen on the surface, liquid in the center. Chefs typically use the technique to develop semifrozen desserts with stable, crunchy surfaces and cool, cream...
Sometimes it's good to just look up important temperatures, like body temperature, the freezing point and boiling point of water, etc. Here are some common important temperatures, in bothCelsius(the metric scale) and Fahrenheit (the US temperature scale): ...
Key point: if you can’t focus, you are really, really fucking stupid Always start with AI (energy, focus, willpower etc). This is the engine we use to power everything else. This means: Learn to get into high-energy deep flow state every day. Key interventions: fix sleep, do inter...

In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
