a statement of the first law of thermodynamics is that a. in a spontaneous process, the entropy of the universe increases b. there is no disorder in a perfect crystal at 0 k. c. the total energy of the universe is constant. d. the totla energy of the universe is constant. e. mass and energy are conserved in all chemical reactions
can only pick one answer i think it is E
Homework Answers
answer : the total energy of the universe is constant
explanation:
first law of thermodynamic is also known as law of conservation of energy . energy can neither created nor be distroyed total energy of the universe is constant . one form of energy is converted into another form.
remaining statements are not suitable for first law:
in a spontaneous process, the entropy of the universe increases---------> it is 2nd law
b. there is no disorder in a perfect crystal at 0 k.----------> it is 3rd law
c. the total energy of the universe is constant.--------> first law
d. the totla energy of the universe is constant. ----------> -------> first law it is given 2 times
e. mass and energy are conserved in all chemical reactions ---------> mass is conserved in chemical reaction but not energy so it is wrong. energy may be released or absorbed so energy not conserved . it will change based on reaction
can only pick one answer i think it is E

Choose the incorrect statement: Gibb's Free Energy is defined as: GH-TS OF AG<0, the process is spontaneous. Of AG > 0, the process is nonspontaneous. The Second Law of Thermodynamics says that all spontaneous processes produce an increases in the entropy of the universe. Of AG-0, the process is spontaneous.
