WebASK AN EXPERT. Science Chemistry A system does 516516 kJ of work and loses 236236 kJ of heat to the surroundings. What is the change in internal energy, Δ?Δ , of the system? Note that internal energy is symbolized as Δ?Δ in some sources. Web19 de out. de 2024 · The internal energy decreases. If the gas is compressed in such a way so that no heat enters or leaves the system, then all the work you do goes into increasing the internal energy, and hence the temperature of the gas. This process is probably what you had in mind. Here the pressure and volume both change, but the … WebThis phenomenon is explained by the second law of thermodynamics, which relies on a concept known as entropy. Entropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work. t shirts s oliver damen
