At $T = 298$ K, $\Delta G$ is:The zeroth law says two systems in equilibrium with a third are:Who formulated the zeroth law of thermodynamics?A wall that does not allow heat to flow is called:A conducting wall that lets heat pass is called:Temperature determines the direction of flow of:The first law of thermodynamics is the general law of conservation of:Which quantity measures the total heat content of a system?Entropy is described as a measure of:A process slow enough to stay in equilibrium throughout is called:A process at constant temperature is called:In an isothermal expansion, heat supplied equals the:A process at constant pressure is called:A process at constant volume is called:In an adiabatic process, the heat absorbed or released is:In an adiabatic process, work done by the gas decreases its:In an isochoric process, the work done is:In an isochoric process the heat absorbed goes entirely to change:Which law forbids a book on a table hopping up by itself?The combination of heat minus work is described as:
