Answer:
hydrogen bonds between water molecules
Explanation:
The hydrogen bonds between water molecules conditions the bulk of its physical property most especially its relatively high boiling point. The hydrogen bond results from the attraction between the oxygen of a water molecule and the hydrogen of another water molecule. The more electronegative oxygen atom causes a distortion and the attraction leads to a strong intermolecular bond between atoms of the water molecules.
Hydrogen bond is a very strong bond and it is responsible for the physical properties of water.
Answer:
In a steam engine into a reciprocating piston cylinder assembly a high pressure steam is been admitted.
Explanation:
Steam engine: High-pressure steam is been injected into a piston-cylinder assembly which is reciprocating in nature. some part of its thermal energy gets converted into movement of the piston to work,When the steam starts expanding to lower pressure.
Apparatus which is separate and a condenser at comparatively low temperature and pressure here steam is passed.The expanded steam can then be made to be free, or, for engine efficiency to be maximum, Rotary motion with a crank-crankshaft assembly similar to that used in automobiles gets transferred from that.
Remaining heat has been now used for warming water.
boiler fired with coal, oil, or natural gas by them the steam gets supplied.
. In many areas, more reliable and economical diesel-electric locomotives gets supplanted by the steam locomotives.
The steam engines today generally are regarded as a unique piece as they are not considered as above reasons are explained.
Nevertheless, the creation of the steam engine played a vital role in the Revolution carried out by the industries by creating a society which now is less dependent on the different windmills, the watermills and mostly the animal power.
