Physical change :) Hope you get it right! :D Good luck! let me know what else I can help you with. Have a great day! :D
''The freezer and room are not an isolated system, since electrical energy flows in.'' is the correct statement.
<h3>
What is Second Law of Thermodynamics?</h3>
The Second Law of Thermodynamics says that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than the energy of the initial state."
So we can conclude that ''The freezer and room are not an isolated system, since electrical energy flows in.'' is the correct statement.

A motion diagram represents the motion of an object by displaying its location at various equally spaced times on the same diagram. Motion diagrams are a pictorial description of an object's motion. They show an object's position and velocity initially, and present several spots in the center of the diagram.
Ok the velocity of an object in free fall is given by the equation :
v=v0-gt, where v0 is the original velocity, g is the gravitational constant (9.8 m/s^2) and t is the time.
so, we substitute values into this equation. v=35.8-9.8*2.5; v=11.3 m/s
