A group of students open several windows to cool off their classroom. After a few minutes, they close the windows. They measure the temperature, and it is 5 degrees cooler than it
was before they opened the windows.
Which statement below best explains why that happened? (Mark the best answer.) (PS3-3)
(1 Point)
The outside air added cold to the air in the room.
The air particles in the room transferred kinetic energy to the air particles from outside.
The air particles mixed so now all the air particles have less kinetic energy.
The outside air particles added kinetic energy to the air particles in the room.

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.
