Mechanical - Engineering Thermodynamics - The Second Law of Thermodynamics. This kind of machine is impossible, as it would violate the first or second law of thermodynamics. Solved Problems: Thermodynamics Second Law.

That is, this would involve a spontaneous increase in organization of molecules or energy which would mean the opposite of energy spreading out.Ī device that violates the Second Law of Thermodynamics is formally known as a perpetual motion machine of the second kind. A perpetual motion machine is a hypothetical machine that can do work indefinitely without an energy source. This is because i t would require the energy to become spontaneously more concentrated in order for the opposite process to occur. No material can spontaneously gain thermal energy from colder surroundings. Gases expand from a high pressure to a low pressure.

A discussion of the Carnot cycle can be found in Wallace & Hobbs. The Second Law of Thermodynamics is concerned with the maximum fraction of a quantity of heat that can be converted into work. Physical processes in nature can proceed toward equilibrium spontaneously: Water flows down a waterfall. Second Law of Thermodynamics The First Law of Thermodynamics is a statement of the principle of conservation of energy. The dye molecules diffuse and spread itself as evenly as possible throughout the volume of water.Ģ. Making snowballs will always make ones hands colder, because thermal energy always flows in a hot-to-cold direction. The Second Law of Thermodynamics The second law of thermodynamics states that processes occur in a certain direction, not in just any direction. A drop of dye when placed in a beaker of water will eventually result in an evenly coloured solution, even without stirring. Identify whether a process follows or violates Second Law of Thermodynamics The process which follow second law of thermodynamics:ġ.
