WebJan 26, 2024 · A good way to model the thermodynamics of a system like this (that involves sliding friction) is to treat the interface between the bodies (the sandpaper and the table) as a separate thermodynamic sub-system. The interface has no mass, so its change in internal energy is always zero. ... It is not the mechanical work done on the sandpaper, but ... WebThe first law of thermodynamics asserts that energy must be conserved in any process involving the exchange of heat and work between a system and its surroundings. A machine that violated the first law would be called a perpetual motion machine of the first kind because it would manufacture its own energy out of nothing and thereby run forever. Web(c)no mechanical work is done by the system. (d)all parameters remain constant. (e)mass and energy transfer do not take place. Ans: c 92. According to first law of thermodynamics (a) work done by a system is equal to heat transferred by the system (b) total internal energy of a system during a process remains constant (c)internal energy ... crimson sandals
