Temperatura is the reading acquired from a thermometer, which quantifies how hot or cold a thing is. At a microscopic level, temperatura defines the average kinetic energy of molecules inside a substance or system. It is a measurable physical attribute of an item. It may be studied alongside other measurable physical qualities such as velocity, mass, and density (to mention a few) (to name a few).
Temperatura is normally viewed in units of degrees Celsius or °C (in certain countries, the Fahrenheit scale is used); but, in the scientific community, the temperatura is observed in SI units—Kelvin or K (note it’s Knot °K). Both Kelvin and Celsius scales have their pros and disadvantages:
Celsius versus Kelvin
The Celsius and Kelvin scales rise by the same increments, indicating that raising the temperatura by one °C results in the same increase of 1 K. The key difference is that when water freezes, a Celsius thermometer will read 0°C, whereas a Kelvin thermometer will read 273.15 K. The scales vary by 273.15. Thus, to convert from °C to K, just add 273; if a thermometer reads 31°C, then the temperatura in Kelvin is 304K.
Celsius is a considerably more “user friendly” or intuitive method to measure temperatura ; at 0°C—water freezes, and at 100°C—water boils. Celsius makes sense, and it’s far simpler to assess how 25°C could feel than how 298 K would, and to be clear, 298 K would feel good.
Why bother with Kelvin?
The Kelvin scale tends to be incredibly helpful (and required) when undertaking scientific calculations and observations. Absolute zero is 0 K (converted to Celsius it’s -273.15°C) and is the lowest temperatura laws of physics allow—there could never be temperaturas below 0 K. In this view; it makes perfect sense to adopt the Kelvin scale, 0 being the “absolute” lowest and ascending from there. For further information (and a useful calculator), check the page, Kelvin.
Because temperatura measures the tiny energy of atoms (or molecules), the temperatura doubles if the microscopic energy doubles. That being said, moving from 10°C today to 20°C tomorrow isn’t double the temperatura (even if 20 is twice ten) (even though 20 is twice ten). A scientist would state it’s 283 K, and here is where the trouble arises: doubling 283 K is 566 K which translates to an excessive 293°C. Thankfully, 293°C will never happen on Earth, but this concept of a proportionate rise in temperatura has led to some climate change uncertainty.
Climate change confusion
An overwhelming number of scientists think that climate change is a big threat confronting the planet. Most climate experts estimate a 1 percent rise in the average world temperatura by the year 2100. This amount seems minor if thinking in Celsius; however, a 1 percent shift implies the Kelvin scale must be utilized. Unfortunately, to complete this calculation, the figures have to be changed to Kelvin. After making the correct conversions and computations, an increase of 1 percent on the Kelvin scale would result in an average world temperatura of 17.4°C by 2100. This may not seem very high, but a rise of 2.9°C is extremely concerning.
