Problem: Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving a crane motor. Lifting against gravity performs mechanical work on the object and stores gravitational potential energy in the object. If the object falls to the ground, gravity does mechanical work on the object which transforms the potential energy in the gravitational field to the kinetic energy released as heat on impact with the ground. Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that in itself (since it still contains the same total energy even if in different forms), but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy.
Give one example of energy transformation.

Answer: generating electric energy from heat energy via a steam turbine


Problem: The largest cemetery is the Cementerio del Norte, located in the northern-central part of the city. The Central Cemetery (Spanish: Cementerio central), located in Barrio Sur in the southern area of the city, is one of Uruguay's main cemeteries. It was one of the first cemeteries (in contrast to church graveyards) in the country, founded in 1835 in a time where burials were still carried out by the Catholic Church. It is the burial place of many of the most famous Uruguayans, such as Eduardo Acevedo, Delmira Agustini, Luis Batlle Berres, José Batlle y Ordóñez, Juan Manuel Blanes, François Ducasse, father of Comte de Lautréamont (Isidore Ducasse), Luis Alberto de Herrera, Benito Nardone, José Enrique Rodó, and Juan Zorrilla de San Martín.
What year was the Central Cemetery founded?

Answer: 1835


Problem: In England, Presbyterianism was established in secret in 1592. Thomas Cartwright is thought to be the first Presbyterian in England. Cartwright's controversial lectures at Cambridge University condemning the episcopal hierarchy of the Elizabethan Church led to his deprivation of his post by Archbishop John Whitgift and his emigration abroad. Between 1645 and 1648, a series of ordinances of the Long Parliament established Presbyterianism as the polity of the Church of England. Presbyterian government was established in London and Lancashire and in a few other places in England, although Presbyterian hostility to the execution of Charles I and the establishment of the republican Commonwealth of England meant that Parliament never enforced the Presbyterian system in England. The re-establishment of the monarchy in 1660 brought the return of Episcopal church government in England (and in Scotland for a short time); but the Presbyterian church in England continued in Non-Conformity, outside of the established church. In 1719 a major split, the Salter's Hall controversy, occurred; with the majority siding with nontrinitarian views. Thomas Bradbury published several sermons bearing on the controversy, and in 1719, "An answer to the reproaches cast on the dissenting ministers who subscribed their belief of the Eternal Trinity.". By the 18th century many English Presbyterian congregations had become Unitarian in doctrine.
