circular bandage with the moment of of a According to the first law of thermodynamics energy does not disappear and does not arise again, and only passes from one form in another. The second law of thermodynamics asserts that all energy eventually passes in thermal energy, and the matter organisation becomes completely disorder. In more strict form this law is formulated so: entropy of the closed system can increase only, and the quantity of useful energy (i.e. that with which help work can be made) in system can decrease only. As entropy understand degree of disorder of system. 7.острый. Теплопроведение (conduction) - heat return at direct contact of a body with other physical objects.
