The first law of thermodynamics is merely the law of conservation applied to the transformation of heat into work. It may be stated as follows: when work is expended in producing heat the quantity of heat generated is equivalent to the work done; and conversely, when heat is employed to do work, a quantity of heat precisely equivalent to the work done disappears.
The second law of thermodynamics is essentially the law of degradation of energy. Whereas the first law gives a relation that must be satisfied in any transformation of energy, it is the second law that gives information regarding the possibility of transformation and the availability of a given form of energy for transformation into work. A general statement of the second law is: “No change in a system of bodies that takes place of itself can increase the available energy of the system”.

Thermodynamics is that branch of physics which deals with the conversion of mechanical energy into thermal energy and the reverse process of transforming heat into work.
The production of heat by mechanical means may be illustrated by the phenomenon of friction. For example, fire may be started while rubbing together two sticks of wood. Heat is developed when compressing a gas. The transformation of heat into work may be illustrated by operation of a steam or gas engine by means of which heat may be transformed into mechanical energy.
So a heat engine is a machine for transforming heat into mechanical energy, the most important of the practical heat engines being the steam engine and the internal combustion engines.

In old Roman legends, Mercury was the swift-footed messenger of the gods. The year on the planet of Mercury is only 88 earth days.
Mercury always keeps one side towards the sun. On this side it is always day, on the other side it is always night. We see only the lighted side.
Mercury appears to us like a yellowish-orange star. The nearest planet to the sun, it is always seen near the sun, either before sunrise or soon after sunset. People sometimes call Mercury the morning or evening star, though it is really a planet.
On its lighted side Mercury’s temperature is about 300 degrees Centigrade. But the dark side is deathly cold — about 150 degrees below zero. So Mercury is probably the coldest, as well as the hottest of the planets.

The ZX 1000 electric 1_______ has two speeds: the fast speed is 3,000 rpm and the slower speed is 1,000 rpm. Adjust the speed according to the 2_______ of material and the size of the hole. For example, use the faster speed for a soft material such as 3_______ to drill holes smaller than 10 millimetres (10 mm) in diameter but choose the slower speed for holes between 10 and 25 mm. However, for steel, a 4_______ material, use the faster speed for holes smaller than 6.5 mm and choose the slower speed to drill holes between 6.5 and 10 mm.
