Why do wires get hot resistance? Heating a metal conductor makes it more difficult for electricity to flow through it. These collisions cause resistance and generate heat. Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance. What causes low resistance in […]

Why isothermal process is very slow?
Why isothermal process is very slow? The isothermal process is slow because the temperature of the system must remain constant. To maintain a constant temperature, the heat transfer process must happen slowly and keep the temperature equal between itself and an outside reservoir. Which of the following does the internal energy of an ideal gas […]
Is bread reversible or irreversible?
Is bread reversible or irreversible? Matthew Johnson, Math major and autodidact. Unless you consider ‘toast’ bread that was simply warmed and not toasted (which I call ‘raw toast’), then clearly it is irreversible. You have by toasting changed the chemistry in an irreversible way. Heat making chemical changes is not “infinitely close to equilibrium”. Is […]
