WebAnswer: There are examples where a contracting system can do work. For simplicity's sake, let's assume we're dealing with gas in a flexible container. If work's being done on the system, we'd expect to see the energy of the system increase. But, if the system decreases in energy, it means work i...
WebWhen we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function. If the constant is greater than 1, we get a vertical stretch; if the constant is between 0 and 1, we get a vertical compression. The graph below shows a function multiplied by ... WebInternal Energy is defined as the sum of all the energy in a system. This energy can take the form or work or heat. We use the symbol ΔE to represent any changes in the internal energy of the system and account for these changes through work and heat. (1) Δ E = w + q. We know that if we have an exothermic reaction the system loses heat and ...
WebThere's the isometric process, also known as isochoric or isovolumetric, where the change in volume is 0, which meant, remember, that means no work can be done. The work was also 0 for an isometric process. And then there's the adiabatic process where no heat is allowed to flow into or out of the system.
