Q3258860 Física
Uma massa de um gás perfeito, sob temperatura de 27oC é confinada em um recipiente de volume igual a 6,0L, é submetida a uma pressão de 2,5atm.
A esse respeito, analise as afirmativas a seguir.

I. Quando a pressão é elevada em 0,5atm., nota-se uma contração no volume de 1,0L, a temperatura do sistema permanece em 27oC e a transformação é isotérmica.

II. Se considerarmos o recipiente indeformável, seco e fechado por uma tampa plástica e aumentarmos a temperatura para 57oC, a pressão de expulsão da tampa de plástico será 3,75atm.

III. A pressão no interior do recipiente do item II, após a saída da tampa, será igual à pressão atmosférica.

Q3258859 Química
O pH é a sigla usada para o potencial (ou potência) hidrogeniônico, porque se refere à concentração de [H+ ] (ou de H3O+ ) em uma solução. Assim, o pH serve para nos indicar se uma solução é ácida, neutra ou básica.
Sobre o tema, analise as afirmativas a seguir.

I. O método mais preciso para medição de pH é a utilização de um pHmetro. Entretanto, para processos em que não seja adequado usar o medidor de pH ou por simplicidade, são usados indicadores, menos precisos, que mudam de cor em diferentes faixas de pH.

II. Observe que quanto menor o valor do pH, mais ácida a solução será. Isso acontece porque a escala de pH é logarítmica, o que quer dizer que o pH é definido como logaritmo negativo da concentração dos íons [H+(aq)] na base 10: colog [H+] = - log [H+] ; pH = - log [H+]; [H+] = 10-pH, em mol/L.

III. O estômago produz suco gástrico constituído de ácido clorídrico, muco, enzimas e sais. O valor de pH no interior do estômago deriva, principalmente, do ácido clorídrico presente. Sendo o ácido clorídrico um ácido forte, a sua ionização é total em meio aquoso, e a concentração de H+ em quantidade de matéria nesse meio será a mesma do ácido de origem. Assim, uma solução aquosa de ácido clorídrico em concentração 0,01mol L-1 terá pH igual a 1.

Shock of the old: Believe it or not, battery-powered vehicles
have been around since Victorian times.

   The history of the electric car is surprisingly enraging. If you imagine early electric vehicles at all (full disclosure: I didn’t until recently), it will probably be as the quixotic and possibly dangerous dream of a few eccentrics, maybe in the 1920s or 1930s, when domestic electrification became widespread. It’s easy to imagine some stiff-collared proto-Musk getting bored of hunting and affairs, eyeing his newly installed electric lights speculatively, then wreaking untold havoc and mass electrocutions. The reality is entirely different.

   By 1900, a third of all cars on the road in the US were electric; we’re looking at the history of a cruelly missed opportunity, and it started astonishingly early. The Scottish engineer Robert Anderson had a go at an electric car of sorts way back in the 1830s, though his invention was somewhat stymied by the fact rechargeable batteries were not invented until 1859, making his crude carriage something of a one-trick pony (and far less useful than an actual pony).

   It’s debatable whether or not Scotland was ready for this brave new world anyway: in 1842, Robert Davidson (another Scot, who had, a few years earlier, also tried his hand at an electric vehicle) saw his electric locomotive Galvani “broken by some malicious hands almost beyond repair” in Perth. The contemporary consensus was that it was attacked by railway workers fearful for their jobs.

   Despite this unpromising start, electric vehicles had entered widespread commercial circulation by the start of the 20th century, particularly in the US. Electric cabs crisscrossed Manhattan, 1897’s bestselling US car was electric and, when he was shot in 1901, President McKinley was taken to hospital in an electric ambulance. London had Walter Bersey’s electric taxis, and Berlin’s fire engines went electric in 1908; the future looked bright, clean and silent.

   By the 1930s, however, the tide had definitively turned against electric, cursed by range limitations and impractical charging times while petrol gained the upper hand thanks partly – and ironically – to the electric starter motor. The Horseless Age magazine, which vehemently backed the petrol non-horse, would have been delighted. There was a brief resurgence of interest in the late 1960s, when the US Congress passed a bill promoting electrical vehicle development, but nothing much actually happened until the Nissan Leaf sparked interest in 2009. Electric still isn’t quite there yet, battling infrastructure and battery problems that might have been familiar to Anderson and friends.
