Select the correct answer
At constant pressure, a hot system spontaneously gives heat to the surroundings at a lower
temperature. For this process:​

Answer 1

Answer:

correct option is

ΔH and ΔG should be negative

ΔH and ΔG should be negative.

For a process that occurs at constant temperature and pressure, spontaneity can be determined using the change in Gibbs free energy, which is given by:

ΔG=ΔH−TΔS

where the sign of ΔG depends on the signs of the changes in enthalpy (ΔH) and entropy (ΔS), as well as on the absolute temperature (T). The sign of ΔG will change from positive to negative (or vice versa) where T=

ΔS

ΔH
