American Revolutionary War

The American Revolutionary War (17751783), also known as the American War of Independence, was a global war that began as a conflict between Great Britain and its Thirteen Colonies which declared independence as the United States of America. After 1765, growing philosophical and political differences strained the relationship between Great Britain and its colonies. Patriot protests against taxation without representation followed the Stamp Act and escalated into boycotts, which culminated in 1773 with the Sons of Liberty destroying a shipment of tea in Boston Harbor. Britain responded by closing Boston Harbor and passing a series of punitive measures against Massachusetts Bay Colony. Massachusetts colonists responded with the Suffolk Resolves, and they established a shadow government which wrested control of the countryside from the Crown. Twelve colonies formed a Continental Congress to coordinate their resistance, establishing committees and conventions that effectively seized power. British attempts to disarm the Massachusetts militia at Concord, Massachusetts in April 1775 led to open combat. Militia forces then besieged Boston, forcing a British evacuation in March 1776, and Congress appointed George Washington to command the Continental Army. Concurrently, an American attempt to invade Quebec and raise rebellion against the British failed decisively. On July 2, 1776, the Continental Congress voted for independence, issuing its declaration on July 4. Sir William Howe launched a British counter-offensive, capturing New York City and leaving American morale at a low ebb. However, victories at Trenton and Princeton restored American confidence. In 1777, the British launched an invasion from Quebec under John Burgoyne, intending to isolate the New England Colonies. Instead of assisting this effort, Howe took his army on a separate campaign against Philadelphia, and Burgoyne was decisively defeated at Saratoga in October 1777. Burgoyne's defeat had drastic consequences. France formally allied with the Americans and entered the war in 1778, and Spain joined the war the following year as an ally of France but not as an ally of the United States. In 1780, the Kingdom of Mysore attacked the British in India, and tensions between Great Britain and the Netherlands erupted into open war. In North America, the British mounted a "Southern strategy" led by Charles Cornwallis which hinged upon a Loyalist uprising, but too few came forward. Cornwallis suffered reversals at King's Mountain and Cowpens. He retreated to Yorktown, Virginia, intending an evacuation, but a decisive French naval victory deprived him of an escape. A Franco-American army led by the Comte de Rochambeau and Washington then besieged Cornwallis' army and, with no sign of relief, he surrendered in October 1781. Whigs in Britain had long opposed the pro-war Tories in Parliament, and the surrender gave them the upper hand. In early 1782, Parliament voted to end all offensive operations in North America, but the war continued in Europe and India. Britain remained under siege in Gibraltar but scored a major victory over the French navy. On September 3, 1783, the belligerent parties signed the Treaty of Paris in which Great Britain agreed to recognize the sovereignty of the United States and formally end the war. French involvement had proven decisive,Brooks, Richard (editor). Atlas of World Military History. HarperCollins, 2000, p. 101 "Washington's success in keeping the army together deprived the British of victory, but French intervention won the war." but France made few gains and incurred crippling debts. Spain made some minor territorial gains but failed in its primary aim of recovering Gibraltar. The Dutch were defeated on all counts and were compelled to cede territory to Great Britain. In India, the war against Mysore and its allies concluded in 1784 without any territorial changes.

Properties of water

Water is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". It is the most abundant substance on Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. It is also the third most abundant molecule in the universe. Water molecules form hydrogen bonds with each other and are strongly polar. This polarity allows it to separate ions in salts and strongly bond to other polar substances such as alcohols and acids, thus dissolving them. Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 °C for its molar mass, and a high heat capacity. Water is amphoteric, meaning that it is both an acid and a base—it produces + and - ions by self-ionization.
