I am by no means a castle expert, but I know a thing or two about building houses. Also I think its safe to say that 'heating techniques' probably varied by region and epoch.
The Short answer is: 1. Heated 'masses'. and 2. building fire was a science to people.
A common house design going back a couple hundred years includes a centrally located large fireplace and hearth to serve various purposes. Seeing as fire was the most advanced technology the people in question had at the time, fire would have been very central in their lives.
A large fireplace capable of safely burning full size logs, several feet long would need to be sturdily built. With brick or stone enclosures (and chimneys) several feet thick.
A fire place 5' tall x 7' long x 4' deep, could possibly involve over 100 cubic feet of stone heated to 800 or 900 degrees. There is what you call a 'heated mass'. Five or Six or who knows how many strategically placed large fires could certainly provide enough heat for a large structure.
Furthermore the actual building of a fire was a highly advanced skill for both men and women. They understood that different types of material burn at different rates, lights, and heats. If somebody had the means, one could have materials (wood) from other regions brought to them.
Castles built after about the year 1200 could be built with chimneys, which were new technology at the time, and could be heated by fireplaces in the various rooms. This was not common, however.
Most castles were heated by building fires on hearths or braziers in the middles of rooms and allowing the smoke to rise to the roof and be vented from there. This meant that the rooms that were heated had to be big enough and high enough for such a fire, and this was the reason a castle would have a room in it called the Great Hall. One of the reasons castles were drafty was that venting the fire required the equivalent of an open window at the top of the room. Other rooms were normally not heated.
Smaller rooms could be heated by using a hearth at the side of the room if the wall was made of stone and the hearth had a smoke canopy. A smoke canopy was a device that gathered the smoke to vent it out through a hole in the roof or wall. I have seen a number of pictures of them, but all of these were in kitchens. They may have been used in some other rooms, but it would appear it was not a common practice. The related question below on smoke canopies has links to pictures.
There were places, particularly Spain, where an ancient system of heating was maintained and used in castles. In this system, called a hypocaust, a fire was used to heat an air space under the floor. Such a system was expensive, and in most of Europe people probably did not even know about it.

no. rulers in ancient Greece lived in palaces (with lots of columns and marble) castles are from the medieval Europe period and developed much later
From central Spain the family crest goes along the lines of defenders of castles
Cleopatra never accomplished much of any significance. Her main accomplishment was her deal with Caesar which gave her the throne. Her other "accomplishments" would be giving birth to four children who lived.
Central HeatingCentral heating appears to have been invented in ancient Greece, but it was the Romans who became the supreme heating engineers of the ancient world with their hypocaust system. Central heating was adopted for use again in the early 19th century when the Industrial Revolution caused an increase in the size of buildings for industry, residential use, and services.

There is no particular year, but most castles had fires to keep warm. For more information on life in castles read this:http://www.castles.org/Kids_Section/Castle_Story/inside.htm

No, traditional castles did not have electricity as they were built before the discovery and harnessing of electricity. Modern castles or castle-like structures may have been retrofitted with electricity for lighting, heating, and other modern amenities.
Physical, or state changes are usually accomplished with heating or cooling
Transfer of heat energy around the Earth from uneven heating of its surface is accomplished by atmospheric circulation patterns. These patterns are driven by the unequal heating of the Earth's surface, creating areas of high and low pressure that result in the movement of air masses. Ultimately, this circulation helps distribute heat energy across the globe.
vaporization. Usually accomplished by excessive heating. Although it depends on which object you are talking about.
Motte and bailey castles, Stone keep castles and Concentric castles
Pasteurization preserves food by killing the bacteria that cause food spoilage. It is accomplished by heating foods to a high temperature.
the first kind of castles were moat and bailey castles.
there are two different types of castles. one is the royal castles and the private castles.
