GAY-LSAC’S LAW

Gay-Lsac’s law is a gas law which stat that the prsure exerted by a gas (of a given mass and kept at a nstant volume) vari directly wh the absolute temperature of the gas. Gay-Lsac’s law impli that the rat of the ial prsure and temperature is equal to the rat of the fal prsure and temperature for a gas of a fixed mass kept at a nstant volume.

When a prsurized aerosol n (such as a odorant n or a spray-pat n) is heated, the rultg crease the prsure exerted by the gas on the ntaer (owg to Gay-Lsac’s law) n rult an explosn.

Gay-Lsac’s law stat that the prsure and temperature of an ial gas are directly proportnal, assumg nstant mass and ’s law or Amonton’s law stat that the absolute temperature and prsure of an ial gas are directly proportnal, unr ndns of nstant mass and volume.

GAY-LSAC’S LAW – DEFN, FORMULA, EXAMPL

Gay-Lsac formulated the law 1802, but was a formal statement of the relatnship between temperature and prsure scribed by French physicist Guillme Amonton the late 1600’’s law stat the temperature and prsure of an ial gas are directly proportnal, assumg nstant mass and ’s Law FormulaHere are the three mon formulas for Gay-Lsac’s law:P ∝ T(P1/T1) = (P2/T2)P1T2 = P2T1P stands for prsure, while T is absolute temperature. Exampl of Gay-Lsac’s Law Everyday LifeHere are exampl of Gay-Lsac’s law everyday life:Tire prsure: Automobile tire prsure drops on a ld day and soars on a hot day.

Siarly, halvg the absolute temperature halv the Gay-Lsac’s and Amonton’s LawsGay-Lsac stated that all gas have the same average thermal expansivy at nstant temperature and prsure. Gay-Lsac's law is an ial gas law which stat that at nstant volume, the prsure of an ial gas is directly proportnal to s absolute temperature ( Kelv). Gay-Lsac is sometim creded as beg the first to state Dalton's law, which says that the total prsure of a gas is the sum of the partial prsur of dividual gas.

GAY-LSAC'S LAW DEFN

The example problems e Gay-Lsac's law to fd the prsure of gas a heated ntaer as well as the temperature you would need to change the prsure of gas a ntaer.

Gay-Lsac's law is a form of the ial gas law which gas volume is kept volume is held nstant, prsure of a gas is directly proportnal to s ual equatns for Gay-Lsac's law are P/T = nstant or Pi/Ti = Pf/ reason the law works is that temperature is a measure of average ketic energy, so as the ketic energy creas, more particle llisns occur and prsure creas. To solve the problem, jt work through the followg steps:The cylr's volume remas unchanged while the gas is heated so Gay-Lsac's gas law appli. Gay-Lsac's gas law n be exprsed as:Pi/Ti = Pf/TfwherePi and Ti are the ial prsure and absolute temperaturPf and Tf are the fal prsure and absolute temperatureFirst, nvert the temperatur to absolute = 27 C = 27 + 273 K = 300 KTf = 77 C = 77 + 273 K = 350 KUse the valu Gay-Lsac's equatn and solve for = PiTf/TiPf = (6 atm)(350K)/(300 K)Pf = 7 atmThe answer you rive would be:The prsure will crease to 7 atm after heatg the gas om 27 C to 77 C.

In 1804 Gay-Lsac ma several darg ascents of over 7, 000 meters above sea level hydrogen-filled balloons—a feat not equaled for another 50 years—that allowed him to vtigate other aspects of gas. In 1808 Gay-Lsac announced what was probably his sgle greatt achievement: om his own and others’ experiments he duced that gas at nstant temperature and prsure be simple numeril proportns by volume, and the rultg product or products—if gas—also bear a simple proportn by volume to the volum of the reactants. Wh his fellow profsor at the Éle Polytechnique, Louis Jacqu Thénard, Gay-Lsac also participated early electrochemil rearch, vtigatg the elements disvered by s means.

Gay-Lsac’s law is a gas law that stat the prsure of a gas vari directly wh temperature when mass and volume are kept nstant. The creased energy means the molecul lli wh the walls of the ntaer wh more force, meang higher Gay Lsac’s Law is also sometim lled Amonton’s Law. Gay Lsac’s Law FormulaGay-Lsac’s law giv a formula where prsure and temperature are related to a nstant when volume and mass/mol are held nstant.

Speakg before Put signed the bill to the law on Monday, Tanya Loksha, associate Europe and Central Asia director at Human Rights Watch said: “The 2013 ‘gay propaganda’ law was an unabashed example of polil homophobia, and the new draft legislatn amplifi that broar and harsher ways. The French chemist Joseph Gay-Lsac \((1778-1850)\) tablished the relatnship between the prsure of a gas and s absolute temperature.

GAY-LSAC’S LAW: INTRODUCTN, FORMULA AND DERIVATN

Gay-Lsac’s Law stat that at nstant volume, the prsure of a given mass of gas vari directly wh the gas’s absolute temperature. Gay-Lsac’s Law is very siar to Charl’s Law; the only difference is that a Charl’s Law experiment, the ntaer is flexible, whereas, a Gay-Lsac’s Law experiment, the ntaer is rigid. From Gay Lsac’s Law, we know that the prsure of a given mass of gas vari directly wh the gas’s absolute temperature.

Hence, Gay-Lsac’s Law impli that for a gas of a fixed mass kept at a nstant volume, the ial prsure and temperature rat is equal to the rat of the fal prsure and temperature. This is bee when a prsurized aerosol n (such as a odorant) is heated, the prsure exerted by the gas on the walls of the ntaer creas(owg to Gay-Lsac’s Law) and n rult an explosn.

But the upg 2014 Wter Olympic gam Sochi, Rsia, has st a spotlight on a strg of anti-gays laws passed the last month by Vladimir Put.

‘OUR MERE EXISTENCE IS ILLEGAL.’ AS MOSW TOUGHENS ANTI-GAY LAW, LGBTQ RSIANS FEAR FOR THE FUTURE

On July 3, Put signed a law banng the adoptn of Rsian-born children by gay upl as well as all upl or sgle parents livg untri where marriage equaly exists.

The law will impose sizable f for holdg gay pri ralli or providg rmatn to mors about the lbian, gay, bisexual and transgenr muny. Includ that law is a provisn that allows police officers to arrt and ta (up to two weeks) any foreign natnals or tourists whom they spect to be gay, lbian, or “pro-gay. Media reports suggt that Put may sign an edict that would allow police to remove the children of gay or lbian parents.

Though Rsia crimalized homosexualy jt after the fall of munism 1993, anti-gay sentiments have been on the rise the untry the past few years.

In June, jt before the vote on the "propaganda of nontradnal sexual relatns" bill, gay rights activists attempted to hold a "kissg rally" outsi the Duma, the Rsia legislative buildg, which is loted across the street om Red Square central Mosw. Acrdg to a poll nducted June by the All-Rsian Public Opn Center (VTSIOM), 54% of rponnts believed that homosexualy should be banned and crimalized.

Sce the first law on “gay propaganda” passed 2013, Rsia has seen repeated crackdowns on the gay muny, most notably 2017 and aga 2019 the southern regn of Chechnya, where activists reported dozens of men and women were taed and some tortured and killed for their sexual orientatn, and no proper vtigatn followed.

“This is not only an anti-gay law, this is also explicly an anti-trans law, ” said Vanya Solovey, an advocy and program officer for Eastern Europe and Central Asia at the trans rights group Transgenr Europe, referencg the part of the package that forbids the promotn of rmatn that uld e people to want to change their genr assigned at birth.
