How hot is really hot- Feel the heat!
Temperature is defined as the degree of heat present in an object. Measured by a thermometer, there are various objective scales for measuring temperature such as the Celsius, Fahrenheit and Kelvin scale. However, how hot or cold an object feels is quite relative. For example, ice feels cold and boiling water feels hot. Yet, the boiling water is about 10 times ‘cooler’ than lava from a volcano and about 270 times ‘cooler’ than a lightning bolt. We all know that -2730 Celsius is called absolute zero or the lowest temperature that is theoretically possible. But what about hotness- how hot is really hot? Is there an absolute maximum temperature and what’s the maximum temperature that we’ve been able to record or create? In this article, we look at the heat scale, how progressively hot things get & the hottest temperature possible in our world and universe.
If you’ve been to a “hot” place or experienced “high” temperatures during summers, you’ve most certainly felt your “eyes burn”. Or, if you’ve spilled hot coffee on yourself, you’ve probably experienced burns and blisters. The difference between the two is about 500 Celsius and yet, we use the words – “hot”, “burning”, “scorching” or “blistering” in both cases! Furthermore, they are not even a fraction of how hot you can experience on Earth itself, leave aside the rest of the Universe. In a controlled nuclear fusion, the temperature can be a million times that of a hot coffee and even then, that’s about 50000 times cooler than the maximum temperature created by mankind!
