The Eternal Thing

    We know the process of Condensation-conversion from vapour to liquid at a given temperature. What's the conversion from gas to liquid at a given temperature called..?     Doesn't this sound stupid? Like, what's the deal in calling a gas and vapour? Well, if you already know the answer, yeah, you are right. A gas never changes to liquid at a fixed temperature..!     Condensation works by increasing the pressure so that matter changes to liquid, a more contained form. But on the other hand, a gas, irrespective of how much high pressure you apply, never reaches the liquid state.      Does that mean we can never liquefy the gas? Of course, it's absurd. We have to control the other parameter, temperature. You reduce the temperature, and yeah, it changes to a liquid.  To give you a little more info, the temperature, after which we can never liquefy, is called "Critical Temperature."      Above the critical temperature, we call it gas. Here, you should reduce tem

  Author: Rama Subrahmanyam Hello, how are you doing..?         We all know that Windows is a super cute-looking OS, but software people will connect to Linux; It offers much flexibility with file management, and plus, it's open-source too..!         So, the book - Linux 101 Hacks, is a nice intro for beginners, by Ramesh Natarajan . Having said that, we look at the top 5 hacks from the book. It is a free e-book, and you can download it here . 1. 'alias' for most used commands:-     There will be commands that are used repeatedly, for which we can have a shortcut using an alias. For example, for cd commands, we can have            alias cd1="cd .."           alias cd2="cd ../.."           alias cd3="cd ../../.."           alias cd4="cd ../../../.."           alias cd5="cd ../../../../.." *Put these in your .bashrc to save permanently. 2. 'ctrl-r' to search:-     Pressing the up arrow till you reach that one previous
