Mass and mucentration data
sara's friend mike also decided to her out with her experiment, like you did. he designed an
investigation where he used pucks with different masses and hit them all with the same amount of force.
in order to be sure he hit the puck with the same amount of force each time, he asked sara if he could
borrow her robotic hockey stick swinging machine, and set the length of the swing to 40 cm every time.
check-in: why do you think mike wanted to hit the different pucks with the same force every time?

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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.
