How do you think dolphins find food in dark water, especially if what they are looking for does not make any noise? What other
sense might they use to "see” without using their eyesight?

Dolphins use the sense (sound) to find food in dark water.

Explanation: Echolocation allows dolphins to “see" by interpreting the echoes of sound waves that bounce off of objects near them in the water. To echolocate objects nearby, dolphins produce high-frequency clicks. ... This information is critical for dolphins to find food and navigate in dark or murky waters.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
