Many languages are spoken, or historically have been spoken, in the United States. Today over 350 languages are used by the U.S. population. The most commonly used language is English (specifically, American English), which is the de facto national language of the United States. Since the 1965 Immigration Act, Spanish is the second most common language in the country. The United States does not have an official language, but some state governments recognize specific languages. For instance, the governments of Louisiana offers services and documents in French, as does New Mexico and Puerto Rico in Spanish. There are many languages indigenous to North America or to U.S. states or holdings in the Pacific region. Hawaiian, although having few native speakers, is an official language along with English of the state of Hawaii. Alaska officializes English and twenty native languages.

According to the currently accepted laws of physics, there is no way to extract chemical energy from water alone. Water itself is highly stable--it was one of the classical elements and contains very strong chemical bonds. Its enthalpy of formation is negative (-68.3 kcal/mol or -285.8 kJ/mol), meaning that energy is required to break those stable bonds, to separate water into its elements, and there are no other compounds of hydrogen and oxygen with more negative enthalpies of formation, meaning that no energy can be released in this manner either.

is it possible to use water as fuel?

A: no

There are at least 35 named glaciers in Glacier National Park (U.S.). In 1850, the area now comprising the national park had 150 glaciers. There are 25 active glaciers remaining in the park today. Since the ice ages stopped 10,000 years ago, there have been many slight climate shifts causing periods of glacier growth or melt-back. The glaciers are currently being studied to see the effect of global warming It is estimated that if current warming trends continue, there will be no glaciers left in the park by 2030.

In 2016, the Australian dollar was the fifth most traded currency in the world, accounting for 6.9% of the world's daily share (down from 8.6% in 2013). It trades in the world foreign exchange markets behind the US dollar, the euro, the yen and the pound sterling. The Australian dollar is popular with currency traders, because of the comparatively high interest rates in Australia, the relative freedom of the foreign exchange market from government intervention, the general stability of Australia's economy and political system, and the prevailing view that the Australian dollar offers diversification benefits in a portfolio containing the major world currencies, especially because of its greater exposure to Asian economies and the commodities cycle. The currency is commonly referred to by foreign-exchange traders as the ''Aussie dollar''.

are us dollars the same as australian dollars?

A:
no
