Energy is conserved in chemical reactions, so the total amount of energy in the universe at the end of a reaction is the same as it was before the reaction.

Every energy transfer or transformation increases the entropy of the universe and some energy is always lost as heat with every energy transfer or energy transformation.Group of answer choicessecond law of thermodynamicsfirst law of thermodynamicsNext

The law of conservation of matter states that during any chemical reaction:the total number of atoms remains the same but some atoms may switch from one element to anotherthe number of atoms of each element remains the samea small amount of matter is converted into energythe total number of molecules remains the same

Every time energy is converted from one form to another, __________.View Available Hint(s)for Part Athe amount of energy in the universe decreasesentropy decreasesthe amount of energy in the universe increasesentropy increases

The Second Law of Thermodynamics states that:Question 9Select one:a.all spontaneous processes happen quicklyb.the total entropy in the universe is always increasingc.the entropy of pure crystalline substances at 0 K = 0d.the total energy in the universe is a constante.The total energy in the universe is variable

Which of the following is true for a universe without dark energy and with positive total energy?The recommended time to answer this question is 2.5 minutes.Soru 9YanıtThe potential energy of such a universe is more dominant than its kinetic energy.The curvature parameter of such a universe is k=0.Such a universe is called a closed universe.Such a universe starts with the big bang, expands for a while, and then contracts again.A two-dimensional representation of such a universe is like a saddle.
