The kinetic theory of an ideal gas assumes exactly the opposite: that there are no forces of attraction or repulsion between molecules except during the brief moment of a collision.

Temperature is a measure of the average kinetic energy of the particles of a substance, in a solid as in a gas: in a solid the particles are held in fixed positions but vibrate about them, and heating makes the vibrations faster and wider, so the average kinetic energy rises…

The kinetic theory gives the average kinetic energy of a molecule as three halves of the product of the Boltzmann constant and the absolute temperature, and for one mole as three halves of RT.

Graham's law of diffusion states that at the same temperature and pressure the rate at which a gas diffuses is inversely proportional to the square root of its density, and therefore of its molar mass.

Substituting one mole, 273.15 kelvin and one atmosphere in the ideal gas equation gives a volume of 22.4 litres, the molar volume at standard temperature and pressure, and this is the figure used in mole calculations; with the modern standard pressure of one bar the value works out to about…

In SI units the universal gas constant is 8.314 joule per mole per kelvin, obtained by multiplying the Boltzmann constant by the Avogadro number.

Extending the straight line of Charles's law backwards shows that the volume of an ideal gas would become zero at minus 273.15 degrees Celsius, and this point is taken as the zero of the kelvin or absolute scale, at which molecular motion carries its least possible energy.

By Charles's law the volume of a fixed mass of gas at constant pressure is proportional to its absolute temperature, so heating the air inside the envelope makes it expand; some of it escapes from the open mouth, the mass of air left inside falls, its density becomes lower than…

Boyle's law, established in 1662, says that for a fixed mass of gas at constant temperature the product of pressure and volume stays constant, so doubling the pressure halves the volume.

The correct answer is TechHive, described as a dedicated platform created to connect mobility start-ups with the wider automotive ecosystem, where emerging companies can show their innovations and meet industry leaders, technology experts, investors, possible customers and collaborators.

The series started in that year as the International Pacific Conference and has since grown into a collaborative automotive engineering forum representing 11 countries across the Asia-Pacific region.

The two-day conference will bring the Asia-Pacific mobility engineering community together at that venue.

The announcement was issued by the Ministry of Heavy Industries.

In anodizing the clean aluminium article is indeed the anode, but oxygen is released at the anode, not at the cathode; hydrogen is released at the cathode.

The Research Design and Standards Organisation (RDSO) is the sole research and development wing of the Ministry of Railways. RDSO is headquartered at Lucknow.

At the outreach the Air Force listed four areas needing focused attention: indigenous propulsion, autonomous software, resilient navigation and standardised interfaces, all of them meant to cut dependence on external sources and strengthen the domestic defence ecosystem.

Around 100 representatives of drone companies and allied industry partners attended, which the Air Force treated as a measure of its growing engagement with the unmanned ecosystem in the country.

The roadmap was released there on 14 September 2026, and the Industry Outreach Programme of 21 October 2026 at Vigyan Bhawan in New Delhi was built on it, with the roadmap booklet distributed to industry partners on that day.

The base is made thin and lightly doped so that most charge carriers from the emitter cross it to the collector.

Ravi K. Budigina was the runner-up in that race at the Asian Para Games 2026, and the Prime Minister called his determination, hard work and sporting spirit commendable, described the achievement as a proud moment for the nation and wished him continued success in the times ahead.
