This whole relationship between pressure, temperature, volume (and density for that matter) is best explained by the ideal gas law equation, at least in a perfect world. More volume translates to lower density, since the weight remains constant. This is due to the thermal expansion of the gases in the air corresponding to an increase in volume. And if you're into your cycling numbers you probably also know that temperatures affect air density, and hence drag at a given speed. Just by looking at the weather your intuition may already tell you that temperature and pressure are closely related. We have already seen how a change in temperature involves a change in momentum of the particles, but there are many more connections than just speed-temperature. We can also predict these changes, and use them to our advantage. In physics it is an unavoidable truth, one thing affects another luckily for us, we know almost always how one thing affects another. We're not talking only about different types of thermometers, but also about different scales.Įverything is connected is something we hear a lot, but we barely consider to what extent this is true. We also need to acknowledge the different ways of measuring temperature. Since this is a temperature conversion tool, it is only fair that we talk about units of temperature. Nevertheless, this is not the only thing we will talk about. Thinking about temperature and heat in terms of energy is very useful and helps us understand many of the things that happen around us. It is also interesting to note that once we think of temperature as a form of energy it becomes fairly clear that our body burns more calories when we try to burn calories by running vigorously, which, incidentally creates much more heat inside our bodies than light exercise. But this would, then, become a large essay on the physical concept of temperature and there would not be space for a conversion tool.įortunately, we have the time and space to point out some interesting facts about temperature, like how any friction will end up creating heat, by converting kinetic energy from one source to another (and therefore increasing the temperature). Or the fact that when we mention speed we should technically speak of the average of all the speeds of all the particles. This is very closely related to the concept of thermal energy and means that heat is just another expression of kinetic energy.Īs always, there's much more to these concepts than what we've mentioned here, like for example the fact that speed is related to the kinetic energy by means of a square root. ![]() What this means is that the higher the temperature of something, the higher the particles velocity a.k.a.the molecules that make up that something vibrate faster. There is no need to worry, however, because when we dig deeper into what is temperature, the answer is fairly simple: temperature is speed, or rather the momentum of the atoms and molecules that make up a material. To do this we have to turn to physics, in particular to thermodynamics and statistical physics, which is like thermodynamics meets quantum physics. We all know what is hot or cold, but temperature? Temperature is much harder to define without getting technical, which is precisely why we will get technical. Because the temperature is no inertia (Faster response to temperature).It is always hard to come up with a good definition for everyday terms, but with temperature, it is notoriously difficult. The NTC is normal thermistor that resistance 10K, or use (5K to 15K) but change the value of R3 and P1 to be proportional, Select Smaller is better. But if used number IC741, offset capacitor (C2) did not enter because there is already a built-in IC. IC1 is common op-amp IC, for example, IC 741, CA3130 or CA3140. IF the output is not 0.5V degrees Celsius, Then increase or decrease the R8 and R9 but to reduce or increase to equal the two. Making the output of the Op-amp with higher voltage. ![]() There are conditions of the NTC, the NTC resistance at higher temperature is decreased, the voltage drop across NTC reduced. The P1 is calibrated to the output of the op-amp is 0V. The voltage across between R1 and R2 have about 3.4V at zero degree Celsius. And R4 is an arm of Bridget’s changing values. There are inputs as bridge circuit includes with R1 to R4, by at R1, R2, R3, and P1 are constant arms of the bridge. The IC1 is op-amp as the difference amplifier.
