IN: James Watt (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.

From an early age Watt was very interested in chemistry. In late 1786, while in Paris, he witnessed an experiment by Berthollet in which he reacted hydrochloric acid with manganese dioxide to produce chlorine. He had already found that an aqueous solution of chlorine could bleach textiles, and had published his findings, which aroused great interest among many potential rivals. When Watt returned to Britain, he began experiments along these lines with hopes of finding a commercially viable process. He discovered that a mixture of salt, manganese dioxide and sulphuric acid could produce chlorine, which Watt believed might be a cheaper method. He passed the chlorine into a weak solution of alkali, and obtained a turbid solution that appeared to have good bleaching properties. He soon communicated these results to James McGrigor, his father-in-law, who was a bleacher in Glasgow. Otherwise he tried to keep his method a secret. With McGrigor and his wife Annie, he started to scale up the process, and in March 1788, McGrigor was able to bleach 1500 yards of cloth to his satisfaction. About this time Berthollet discovered the salt and sulphuric acid process, and published it so it became public knowledge. Many others began to experiment with improving the process, which still had many shortcomings, not the least of which was the problem of transporting the liquid product. Watt's rivals soon overtook him in developing the process, and he dropped out of the race. It was not until 1799, when Charles Tennant patented a process for producing solid bleaching powder (calcium hypochlorite) that it became a commercial success. By 1794 Watt had been chosen by Thomas Beddoes to manufacture apparatus to produce, clean and store gases for use in the new Pneumatic Institution at Hotwells in Bristol. Watt continued to experiment with various gases for several years, but by 1797 the medical uses for the "factitious airs" had come to a dead end.

Why is bleach sold as a liquid then?

IN: Feeder are a Welsh rock band formed in Newport, Wales. They have released ten studio albums, twelve compilations, four EPs, and 40 singles. They have spent a total of 182 weeks on the singles and albums charts combined as of 2017, and have accumulated 25 top 75 singles between 1997 and 2012. At their peak of commercial success, Feeder won two Kerrang!

For 1999's Yesterday Went Too Soon, the band decided to self-produce the album, brought in Matt Sime for engineering duties and had the album mixed in New York by Andy Wallace. "Dry" was re-recorded as a full band version after the original acoustic version appeared on "Suffocate" as a b-side. That single's b-sides featured tracks from the sessions for that album, therefore revealing what sort of direction it would take on. The working title for the album was originally A Life Through Headphones, and was originally set to be a double album. The name change was due to former Take That singer Robbie Williams releasing his solo debut album Life Thru a Lens, with the band not wanting to be compared to him. When the album was released, the band's reputation was on the rise and it entered the UK albums chart at number eight, which was at the time an unexpected chart position for the band. Before that, the band had released the album's first single, "Day In Day Out", in March 1999 which charted at #31 followed by "Insomnia" at #22, resulting in their first appearance on Top of the Pops. A week before the album's release, the band played the main stage of the Reading and Leeds festivals, while the title track from the album was at #20 in the singles chart. The album was then released on 30 August 1999. Only one single was lifted from the album after its release, in which a re-recorded version of "Paperfaces" charted at #41. Some of the album's lyrical themes were derived from Grant's personal perspective of working in a menial supermarket job on a daily basis ("Day in Day Out"), his experiences after gigs on their US tour ("Insomnia" and "You're My Evergreen"), past relationships (the title track and "Dry"), the music industry ("Hole in My Head") and "fear of commitment in relationships" ("Anaesthetic") amongst others. Musically, the album employed an indie rock feel to it, which also featured extended appearances of an acoustic guitar on some of its tracks. The album was due for release in June, but this was delayed until August to include material written after its completion which the band felt was too good to leave off. Upon its release, the UK music press immediately warmed to the album, which also received Melody Maker 's Album of the Week accolade. The year ended with the band providing support for the Red Hot Chili Peppers at Wembley Arena and Manic Street Preachers at the Millennium Stadium. As of March 2003, the album has been certified gold shipping 100,000 units in the UK, with total counter sales standing at 110,000 as of February 2005. The album was Melody Maker's #24 album of 1999, while Metal Hammer placed the album in at #6 and Kerrang! ranked it at #16.
