At first, the title might sound pretty weird. But, this is something which most of us have experienced. While roaming outside on a hot day, we usually observe that the heat around us gives off a very peculiar (and not very pleasant) smell. Why do we get this smell? Is it actually the smell of heat? Let’s explore!
First, let us acquaint ourselves with the basics. Heat is a form of energy that gives us the sensation of temperature. If something has a significant amount of heat, we say it is hot, and when something is devoid of heat, we say it is cold. Heat, like most forms of energy, can travel from one material to another through various methods.
Firstly, I would like to tell you that as far as my research is concerned, I have found no reasons for this on any website. So, everything henceforth will purely be my logic. So, please note that it may be incorrect at some places.
Let’s start off with a question: What exactly does heat smell like? Well, as a matter of fact, burning plastic could be the closest match. It isn’t that pleasant and makes you feel worse, as if the sweltering heat wasn’t enough.
Let us now try to reason out as to why heat smells. We know that the air around us contains millions of particles, ranging from oxygen to dust. Now, when air absorbs heat, it tends to move faster (It is the tendency of particles to get excited when energy is provided). Due to this increase in energy, the molecules of air spread out at a rapid pace and accumulate any particulate matter around them.
Next, we know that heat is capable of burning things (I know this is obvious but hear me out). So, the amount of heat the air molecules would be holding might be sufficient to burn the particles suspended in it, as both the size and mass of the particles is very small. The smell given off by heat might as well be that of burning particles within it.
This also happens in heaters which haven’t been used for a long time. Due to accumulation of dust and soot, turning on the heat burns the particles and the heater gives off a very bad odour. So, remember to clean your heaters.
So, how was it? Did it get you all heated up? Feel free to comment in the Comments section.
Stay Safe, Stay Home!
