Gas laws 1662 Robert Boyle studied the relationship between volume and pressure of a gas of fixed amount at constant temperature. He observed that volume of a given mass of a gas is inversely proportional to its pressure at a constant temperature. Boyle's law, published in 1662, states that, at constant temperature, the product of the pressure and volume of a given mass of an ideal gas in a closed system is always constant. It can be verified experimentally using a pressure gauge and a variable volume container. It can also be derived from the kinetic theory of gases: if a container,
The Boy Who Was a King term. The film presents not only the life of the former Tsar, but also intertwines within the story vignettes of various Bulgarians, who were supporting him, sending him gifts, or merely tattooing his face on their body. The story is told through personal footage and vast amounts of archive material. The film received praise for its editing and use of archives with Variety's Robert Koehler writing that "Pic’s terrific use of archival footage includes an exiled Simeon interviewed in the early ’60s, disputing his playboy rep." and "Editing is aces."
