Dewar Flask: What Is A Thermos? How Does A Thermos Work?

September 08,2024

Don’t you agree humans can be contrarian? Like when the winters are on, we hanker for warmth and start making arrangements to keep ourselves warm. And when the summers come, we affix our eyes on the air conditioners to shield ourselves from heat—the same heat we embraced in the winters! Thermos flask is one of such invention which extricates us in our contrarian needs..
Science gets a bad rep for being boring, difficult and for very smart people (see: nerds). But that doesn't have to be the case. At ScienceABC we believe that if science is communicated simply and made relatable and fun, it can be for everyone. As Micheal Jackson said best, as simple as ABC. So far, we've tackled complex and vast topics like Einstein's Time Dilation, the Immune System, Evolution, Quantum Entanglement, while also asking the questions that nag us at night like Is the science in the movies accurate?, Is it possible to have insects the size of humans?, and Why can I hear a thundering sound in my ear?. So, join us for some simple science with a whole lot of fun thrown in! Subscribe to us for your regular dose of science and don't forget to share our work if you liked it.
