Who were the patriots in the Revolutionary War?
Patriots, also known as Whigs, were the colonists who rebelled against British monarchial control. Their rebellion was based on the social and political philosophy of republicanism, which rejected the ideas of a monarchy and aristocracy – essentially, inherited power.
What happened during 1770s?
The Boston Massacre was a deadly riot that occurred on March 5, 1770, on King Street in Boston. It began as a street brawl between American colonists and a lone British soldier, but quickly escalated to a chaotic, bloody slaughter.
Why is 1770 significant?
The town is built on the site of the second landing in Australia by James Cook and the crew of HM Bark Endeavour in May 1770 (and their first landing in what is now the state of Queensland). …
What happened in the US in the 1770s?
1770 AD Boston Massacre Occurs -A group of British soldiers fired on a mob of colonial protesters. One of the British soldiers opened fire, and soon eleven of the colonists were hit, five of whom died. 1772 AD First Partition of Poland Russia, Prussia and Austria agreed on the partition of Poland.
What happened in the US in 1772?
1772 – In June, a British customs schooner, the Gaspee, runs aground off Rhode Island in Narragansett Bay. Colonists from Providence row out to the schooner and attack it, set the British crew ashore, then burn the ship. The announcement that they would be sent to England further upsets many American colonists.
What happened in the US in 1771?

What was the most important impact of the American Revolution?
The Revolution’s most important long-term economic consequence was the end of mercantilism. The British Empire had imposed various restrictions on the colonial economies including limiting trade, settlement, and manufacturing. The Revolution opened new markets and new trade relationships.
Who really discovered oxygen?
Joseph Priestley
Why is oxygen O2 and not o?
Why is oxygen written as O2? The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
Can oxygen be made?
The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air. This method is called electrolysis and produces very pure hydrogen and oxygen.
Is oxygen matter Yes or no?
Air is an example of the type of matter known as gas. Other common forms of matter are solids and liquids. If you analyze air, it consists mostly of nitrogen and oxygen, with smaller amounts of several other gases, including argon, carbon dioxide, and neon.
Is pure oxygen flammable?
Despite popular opinion, oxygen is not flammable. A flammable substance is one that burns. Though oxygen does not burn, it is an oxidizer, which means it supports the process of combustion. So if you already have a fuel and a fire, adding oxygen will feed the flames.
Can you light air on fire?
No. In order for something to be combustible it must have some chemical potential energy that can be released by reacting that something with oxygen. In the case of air, everything is already stable, and it would actually require additional energy to pull it apart in order to bond it with oxygen.
Which is more flammable hydrogen or oxygen?
Hydrogen is flammable, but oxygen is not. Flammability is the ability of a combustible material with an adequate supply of oxygen (or another oxidiser) to sustain enough heat energy to keep a fire going after it has been ignited.
Why does helium change your voice?
But when they go through the helium that you’ve inhaled, they travel about three times faster. That’s because helium is so much lighter than air. It’s a gas that is much heavier than air, so when it is inhaled, it shortens sound waves so the lower tones in the voice are amplified and the higher ones fade out.
What is special about helium?
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties. Helium is the second most abundant element in the known universe, after hydrogen.
Why is helium so expensive?
Helium is often found underground among other natural gases, but to be used, it must be separated out into its pure form, Segre said. That’s an expensive process, and it’s also costly to store, because of its light weight. Natural gas companies often do not do this because of the cost, Segre said.
Why does NASA use so much helium?
NASA uses helium as an inert purge gas for hydrogen systems and a pressurizing agent for ground and flight fluid systems. Helium is required to support the Space Launch System, Orion spacecraft, Stratospheric Observatory for Infrared Astronomy (SOFIA), International Space Station, and various other programs.
Is helium still used in balloons?
It’s the only gas lighter than air except for hydrogen – which is highly flammable. Balloon gas is a mixture of mainly helium and some atmospheric gases. It is a by product of the helium gas industry and cannot be used in science and academic applications.
Can you invest in helium?
Playing the helium market With the vast majority of our helium supply coming from natural gas reservoirs, we think the best and easiest way to play the helium boom is to invest in natural gas companies that own the richest deposits of helium, preferably with helium concentrations of >1.5+%.
