Which example involves a phase change in which heat energy is released by the substance? freezing ice cream cooking a pot of soup melting ice under sunlight watching frost disappear into air

The correct answer would be freezing ice cream.

All the processes are the examples of endothermic reaction except freezing ice cream which is an example of an exothermic reaction.

During freezing, the energy is lost to the surrounding medium due to which the temperature of the substance decreases.

Similarly, in making ice cream the heat from the milk is lost in the surrounding medium due to which the temperature of milk decreases and it gets freezes

explanation:

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
