Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.[note 4] Energy can be transferred between systems in a variety of ways. Examples include the transmission of electromagnetic energy via photons, physical collisions which transfer kinetic energy,[note 5] and the conductive transfer of thermal energy.
What can be considered for the special case of systems which are closed to transfers of matter?
****
The answer: Energy transfer

In January 1950, the Church of Cyprus organised a referendum under the supervision of clerics and with no Turkish Cypriot participation, where 96% of the participating Greek Cypriots voted in favour of enosis, The Greeks were 80.2% of the total island' s population at the time (census 1946). Restricted autonomy under a constitution was proposed by the British administration but eventually rejected. In 1955 the EOKA organisation was founded, seeking union with Greece through armed struggle. At the same time the Turkish Resistance Organisation (TMT), calling for Taksim, or partition, was established by the Turkish Cypriots as a counterweight. The British had also adopted at the time a policy of "divide and rule". Woodhouse, a British official in Cyprus, revealed that then British Foreign Secretary Harold Macmillan "urged the Britons in Cyprus to stir up the Turks in order to neutralise Greek agitation". British officials also tolerated the creation of the Turkish underground organisation T.M.T. The Secretary of State for the Colonies in a letter dated 15 July 1958 had advised the Governor of Cyprus not to act against T.M.T despite its illegal actions so as not to harm British relations with the Turkish government.
In what year did the Church of Cyprus organize a referendum?
****
The answer: 1950

The army was still equipped with the Dreyse needle gun of Battle of Königgrätz fame, which was by this time showing the age of its 25-year-old design. The rifle had a range of only 600 m (2,000 ft) and lacked the rubber breech seal that permitted aimed shots. The deficiencies of the needle gun were more than compensated for by the famous Krupp 6-pounder (3 kg) steel breech-loading cannons being issued to Prussian artillery batteries. Firing a contact-detonated shell, the Krupp gun had a longer range and a higher rate of fire than the French bronze muzzle loading cannon, which relied on faulty time fuses.
What type of shell did the Krupp weapon fire?
****
The answer: a contact-detonated shell


The problem: Answer a question about this article:
Georgian architecture was widely disseminated in the English colonies during the Georgian era. American buildings of the Georgian period were very often constructed of wood with clapboards; even columns were made of timber, framed up, and turned on an over-sized lathe. At the start of the period the difficulties of obtaining and transporting brick or stone made them a common alternative only in the larger cities, or where they were obtainable locally. Dartmouth College, Harvard University, and the College of William and Mary, offer leading examples of Georgian architecture in the Americas.
What was difficult to obtain and transport during the Georgian period?
****
The answer:
brick or stone
