Civil rights movement in the Unites States of America showed that civil disobedience brings the legislative changes, successfully. Any type of injustice, if not tolerated and a voice is raised, then even the governments have to listen and amend the laws.

<h3>
What is refrigeration system?</h3>
Refrigeration systems are crucial processes in business and domestic applications because they provide cooling or maintain a specific room temperature. A refrigeration cycle consists of heat exchange, compression, and expansion with a refrigerant flowing through the cycle's units.
The refrigerants are chemical substances with thermodynamic properties that are ideal for the functioning of a refrigeration cycle. They are often tiny molecules with lower than normal boiling points (usually less than 273 K). However, other safety qualities (such as flammability or auto-ignition temperature) and environmental impact (such as ozone depletion or global warming) influence their selection.

Steam power originally developed slowly over a period of several hundred years until it reached to actual practical application at the beginning of the industrial revolution. The steam engine was one of the most important technologies of the industrial revolution. It was a simple device that used boiling water to create mechanical motion to be utilized in useful work.
Early mills used water power to operate and had to be located near running water such as a river which would freeze in winter and the water was not available, also in dry spells. Flooding would also stop operations. But by using a steam engine, a factory could be located anywhere and could operate the whole year round.
From mines to mills, steam engines found many applications in a variety of industries, improving productivity and technology such as Trevithick's high pressure engine that revolutionized transport. Steam engines found their way to boats, railways, farms and road vehicles.
Answer: The Congress had no authority to levy taxes, and was required to request money, supplies, and troops from the states to support the war effort. Individual states frequently ignored these requests.
