The 2022 World Snooker Championship (officially the 2022 Betfred World Snooker Championship) was a professional snooker tournament that took place from 16 April to 2 May 2022 at the Crucible Theatre in Sheffield, England, the 46th consecutive year the World Snooker Championship was held at the venue. The 16th and final ranking event of the 2021–22 snooker season, the tournament was organised by the World Snooker Tour and sponsored by sports betting company Betfred. It was broadcast in the United Kingdom by the BBC, in Europe (including the UK) by Eurosport, and elsewhere in the world by Matchroom Sport and other broadcasters. The total prize fund was £2,395,000, of which the winner received £500,000.

Qualifying rounds for the tournament took place from 4 to 13 April 2022 at the English Institute of Sport, featuring 128 professional and invited amateur players. The main stage of the tournament featured 32 players: the top 16 players from the snooker world rankings and another 16 players from the qualifying rounds. Ashley Hugill, Jackson Page, and Hossein Vafaei were debutants at the Crucible, Vafaei being the first Iranian player to reach the main stage. Mark Selby was the defending champion, having won the 2021 final 18–15 against Shaun Murphy. He lost 10–13 to Yan Bingtao in a second-round match that produced the longest frame ever played at the Crucible, lasting 85 minutes.

Ronnie O'Sullivan equalled Steve Davis's record of 30 Crucible appearances. He reached a record 20th quarter-final and a record 13th semi-final before defeating Judd Trump 18–13 in the final to equal Stephen Hendry's record of seven world titles. It was O'Sullivan's 39th ranking title and 21st Triple Crown title. Aged 46 years and 148 days, he became the oldest world champion in the sport's history, surpassing Ray Reardon, who was aged 45 years and 203 days when he won his last world title in 1978. O'Sullivan also broke Hendry's record of 70 wins at the Crucible, setting a new record of 74.

Neil Robertson made a maximum break in his second-round match against Jack Lisowski, the fifth of his career and the 12th time a 147 had been achieved at the Crucible. Graeme Dott also made a maximum break in his third-round qualifying match against Pang Junxu, the second of his career and the fifth time that a maximum had been made in the World Championship qualifiers. The main stage produced a record 109 century breaks, surpassing the 108 centuries made the preceding year. Mark Williams made 16 centuries during the event, equalling the record set by Hendry in 2002.</think>

user: Based on the paragraph below, describe 2 suitable applications of noble gases.

assistant: <think>
The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
Oganesson (Og) is a synthetically produced highly radioactive element. Although IUPAC has used the term "noble gas" interchangeably with "group 18" and thus included oganesson, it may not be significantly chemically noble and is predicted to break the trend and be reactive due to relativistic effects. Because of the extremely short 0.7 ms half-life of its only known isotope, its chemistry has not yet been investigated.
For the first six periods of the periodic table, the noble gases are exactly the members of group 18. Noble gases are typically highly unreactive except when under particular extreme conditions. The inertness of noble gases makes them very suitable in applications where reactions are not wanted. For example, argon is used in incandescent lamps to prevent the hot tungsten filament from oxidizing; also, helium is used in breathing gas by deep-sea divers to prevent oxygen, nitrogen and carbon dioxide toxicity.
The properties of the noble gases can be well explained by modern theories of atomic structure: Their outer shell of valence electrons is considered to be "full", giving them little tendency to participate in chemical reactions, and it has been possible to prepare only a few hundred noble gas compounds. The melting and boiling points for a given noble gas are close together, differing by less than 10 °C (18 °F); that is, they are liquids over only a small temperature range.
Neon, argon, krypton, and xenon are obtained from air in an air separation unit using the methods of liquefaction of gases and fractional distillation. Helium is sourced from natural gas fields that have high concentrations of helium in the natural gas, using cryogenic gas separation techniques, and radon is usually isolated from the radioactive decay of dissolved radium, thorium, or uranium compounds. Noble gases have several important applications in industries such as lighting, welding, and space exploration. A helium-oxygen breathing gas is often used by deep-sea divers at depths of seawater over 55 m (180 ft). After the risks caused by the flammability of hydrogen became apparent in the Hindenburg disaster, it was replaced with helium in blimps and balloons.</think>
The inertness of noble gases makes them very suitable in applications where reactions are not wanted. Two suitable examples of application are: 
1. argon is used in incandescent lamps to prevent the hot tungsten filament from oxidizing,
2. helium is used in breathing gas by deep-sea divers to prevent oxygen, nitrogen and carbon dioxide toxicity.

user: Is Davos worth traveling?

assistant: <think>
Davos is an Alpine resort town and a municipality in the Praettigau/Davos Region in the canton of Graubuenden, Switzerland. It has a permanent population of 10,832 (2020). Davos is located on the river Landwasser, in the Rhaetian Alps, between the Plessur and Albula Ranges.

The municipality covers nearly the entire valley of the Landwasser, and the centre of population, economic activity, and administration is two adjacent villages: Davos Dorf (German: Davos Village) and Davos Platz (Davos Place), at 1,560 m (5,120 ft) above sea level.

Gaining prominence in the 19th century as a mountain health resort, Davos is perhaps best known today for hosting the World Economic Forum—often referred to simply as "Davos"—an annual meeting of global political and corporate leaders. With a long history of winter sport, Davos also has one of Switzerland's largest ski resorts, and hosts the international Spengler Cup ice hockey tournament each December.

Davos is a very scenic town in the Swiss Alps. Famous for winter sports like skiing, cross-country skiing, sledding, ice hockey and ice skating and also for the World Economic Forum that take place annually.
