Hello friends, today we will tell you why we feel cold when we put petrol or other on the palm of our hand. And where does that petrol disappear? So let's start friends, the more you increase the surface area of petrol or perfume, the faster it will evaporate. That is, it will become vapour and fly up. But friends must be coming to your mind that anything has to be heated to become vapour.
Only then will its vapor form. But where does petrol get its heat. So friends, it meets him in your palm. The heat that is used to vaporize petrol from the palm is called latent heat, it is the heat that keeps the temperature of that substance constant. That is, without any change in the temperature which is already there, it changes the state of that substance. In this way, they absorb enough heat latent heat from the palm. Due to which they evaporate and disappear. As a result of which our palms feel frosty Friends, because of this latent heat, the ice does not melt at once. Rather slowly it keeps on melting, because of the heat of the outer atmosphere in it. Its temperature remains constant. And the ice keeps melting slowly, hope you have understood this information very well, then if you have any question, then you can ask in the comments below. Friends, we told you here that on putting petrol or other, our palm becomes cold qi. Similarly, on this blog, I give information related to science in daily life, everyday you will get to know something new on this blog.
