  • @EldritchFeminity @infinitesunrise I’m not sure if it’s organized, but it does describe a specific school of thought that isn’t just “I don’t personally want to have kids.” Antinatalists generally believe that it’s unethical for anyone to reproduce. The core argument is usually that since you can’t consent to being born, you can’t ethically impose it on someone against their will. It tends to go hand-in-hand with misanthropic ideas such as that humans are destructive to the planet/fundamentally cruel or that life in general just sucks. Ultimately, the thesis is that humans should extinct ourselves. Given the current state of the world, it’s gained some traction amongst groups of people trapped deep in despair right now. (Which, let’s be real - there are a lot of on Lemmy)

    This also explains why evaporation cools down (like when you sweat): the molecules with the highest temperature are the ones evaporating, so the average temperature decreases as those high-temperature molecules leave the system. Only the relatively colder molecules are left behind - thus it cools as a whole.

    The main principle at work here is the enthalpy of vaporization. When matter changes state, there is an associated amount of energy that is absorbed or released - in the case of vaporization, energy must be absorbed. So when sweat forms on your skin and evaporates, it absorbs heat energy from your body in order to undergo that state change.

    For water, the energy involved here is remarkably high, much higher than the energy stored by a few degrees difference in temperature. For example, if you wanted to boil off 1kg of water, it would take about 300 kJ to bring the temperature up to boiling from room temperature and over 2000 kJ to boil it all into steam.
