Determine the FALSE statement:

In general, the energy to power the human body is taken directly from the sun.


On a macroscopic scale, heat cannot transfer from a cold body to a hot body.


Thermal energy is caused by atomic level kinetic energy.


In an endothermic reaction, heat enters into a system.


Methane, CH4, would have a lower heat capacity than isobutane, CH3CH(CH3)CH3.

Final answer:

In general, the energy to power the human body is not directly taken from the sun. On a macroscopic scale, no heat transfers from a cold body to a hot body atomic level kinetic energy is the source of thermal energy. The correct answer is option a.

Step-by-step explanation:

The FALSE statement in this question is In general, the energy to power the human body is taken directly from the sun. While it is true that the sun is the ultimate source of energy for most life on Earth, the energy to power the human body is obtained through food, which is ultimately derived from plants and animals. The energy in food is stored chemical energy, not directly from the sun.

Every other assertion in the inquiry is accurate. On a macroscopic scale, heat cannot transfer from a cold body to a hot body due to the second law of thermodynamics. Thermal energy is indeed caused by the kinetic energy of atoms and molecules. Heat enters a system during an endothermic process. And methane, CH₄, would indeed have a lower heat capacity than isobutane, CH₃CH(CH₃)CH₃.
