In physical education class, students stand in a straight line against the gym wall. When the teacher blows a whistle, the entire class runs to the other side of the room. Which of the following correctly describes the students’ energy? A. The students gain potential energy as they run across the gym.
B. The students move from a state of potential energy to one of kinetic energy.
C. The students use kinetic energy both when they are stopped and while they are running.
D. The students do not have energy when they are stopped, but they gain energy by running.

D

Explanation:

When dog start running Front of you And you act Already and run away do you think The dog same to your Question

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.
