Which is consistent with the laws of physics governing energy?
A)As a car burns gasoline,100% of the fuel energy goes into moving the car along the road
B)You eat a "quarter-pounder" hamburger and assemble exactly a quarter pound of additional body weight on your body
C)Sunlight that is absorbed on the earth eventually returns to space as dispersed heat
D)Chemical bonds are an example of converting energy to matter;breaking the bonds converts matter to energy

Question

Quizplus · Accepted Answer

According to the law of conservation of energy, energy cannot be created or destroyed, but it can be converted from one form to another. When sunlight is absorbed on earth, it is converted into heat, which eventually dissipates into the atmosphere and returns to space. This process is consistent with the laws of physics governing energy and the principle of conservation of energy.

Answer: D
 Chemical bonds involve the exchange of energy between atoms and molecules. Breaking chemical bonds releases energy, while forming new bonds requires energy. This process is consistent with the laws of physics governing energy, as the total amount of energy in the system before and after the bond formation remains the same. However, the statement in the answer choice is incorrect, as breaking bonds converts matter to other forms of matter (not energy).
