How freely they’re able to move depends on the state of matter of those molecules. States of matterĮven though molecules move all the time when above that lowest possible temperature, that does not mean they move freely. After enough bumps, all molecules will move at about the same speed and thus have the same temperature!Ī hot cup of water with a tea bag, there’s quite some movement of molecules within the water that is beautifully visualized thanks to the darker coloured tea. If one molecule has a lot more energy (aka, is hotter) than another one (which is colder) it will transfer some of that additional energy to the low energy molecule. This is because molecules continuously bump into one another. Molecules transfer kinetic energy to one another.If you place a few very hot and a few very cold molecules in the same room, they will become the same temperature over time (assuming an ideal system). For food this is quite irrelevant though since this absolute zero is at -273☌ (-459☏). There is one situation in which molecules would not move at all: at the lowest temperature possible, the absolute zero. The lower the temperature the lower the kinetic energy of these molecules. Heat, so a higher temperature, gives the energy to move. The lower the temperature, the less movement. Just how much all the matter around us moves depends on the temperature of that matter. Even though it may not seem like it since it happens at such a small scale, these molecules are moving all the time. Carbohydrates, proteins, fats, they’re all molecules. Molecules form the building blocks of our food as well. The whole world around is is filled with molecules. Without even realizing, you’re continuously switching between three* states of matter: solids, liquids and gases to make delicious food.īut how do those transitions even work? Knowing that will allow you to use them even more to your advantage! Moving molecules – Kinetics You melt butter in a hot pan, boil down a runny stock into a thick syrupy consistency or transform a liquid custard into a solid tub of ice cream. When you prepare food you continuously change the states of our ingredients.
