Which of the following is TRUE regarding the second law of thermodynamics?
The quality of the energy in the universe increases over time.

Entropy is conserved in the universe.
this one represents an endothermic reaction. Things are similar: the flat line on
the left (beginning of the reaction) is the total energy possessed by the reactant
molecules; once again, kJ stands for energy in kiloJoules, thousands of Joules.
The flat line on the right (reaction complete) is the total energy of the products.
Since an endothermic reaction has a net absorption of energy (taking this extra
energy from the surroundings), the products have higher energy than the
reactants. Question: the energy of the reactant molecules is
kJ. [to
answer, simply identify the correct y-axis coordinate.]

- You and a friend are eating dinner together, and a number of events occur during your dinner that call to mind the Laws of Thermodynamics. Match each event to the most relevant Law of Thermodynamics. Your food is cooked on a propane grill, which converts the chemical energy from propane and oxygen into the heat used to cook the food, First Law of Thermodynamics Second Law of Thermodynamics Your meals arrive, and your friend enjoys eating her steak, which contains chemical energy that will be converted into other forms of chemical energy within her body. After the meal, you go for a walk. The chemical energy from dinner will help generate ATP to fuel the skeletal muscles used for walking. The waiter brings a basket of bread, but as you eat it crumbs are scattered on the table. Your glass of water falls off the table and breaks into many pieces.arrow_forwardThe existence of life is dependents on bioenergetics to overcome the restrictions of thermodynamics.
