WebIn an isothermal process, 3700 J of work is done by an ideal gas. Is this enough information to tell how much heat has been added to the system? If so, how much? If not, why not? 3700 J Enters System The internal energy of a gas only depends on the temperature. Can mechanical energy ever be transformed completely into heat or internal energy? WebThere are several types of thermodynamic processes, including (a) isothermal, where the system’s temperature is constant; (b) adiabatic, where no heat is exchanged by the system; (c) isobaric, where the system’s pressure is constant; and (d) isochoric, where the system’s volume is constant. lithuanian foreign policy review
