For example, the cost of a CT scanner can be as low as $65,000 for a refurbished one that produces only small images quickly. A larger and brand new CT scanner can run as high as $2.5 million.Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.Ultrasound machines are much cheaper at $10,000-$200,000, depending on brand and type. larger and brand new CT scanner can run as high as $2.5 million.

1 Second law of thermodynamics: In a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems increases. 2  Equivalently, perpetual motion machines of the second kind are impossible.
heating objects, doing work on a system, transferring thermal energy according to the first law of thermodynamics, the amount of work done by a heat engine equals the amount of thermal energy added to the engine minus the waste heat the second law of thermodynamics states that thermal energy can flow from colder to hotter objects when only if work is being done on the system state the 3rd law of thermodynamics
