WebMar 25, 2024 · Explanation: When we graph adiabatics and isotherms, we might do so on a P vs. V diagram, or a pressure vs. volume diagram. Therefore, the slope of any curve on the graph is Δy/Δx = ΔP /ΔV. For an isothermal process, we know that there is no change in temperature, i.e. ΔT = 0. Then, by the ideal gas law, we have: P V = constant.

There's the isometric … toad spirited awayWebThe only way the temperature's gonna remain constant is for 300 joules of heat to leave the gas, 300 joules of heat would have to leave. That would mean that Q is -300 joules, that way 300 joules and -300 joules add up to 0, you've got an isothermal process. But it's not enough for just the initial temperature to equal the final temperature. pennington field tx
