Answer:
D. First law of thermodynamics
Explanation:
The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.
The equation ΔU = Q − W describes the first law of thermodynamics.
Where
- U is the internl energy of the system.
- ΔU is the change in U.
- Q refers to the total heat supplied into the system (include both addition and release of energy in the system).
- W is the net work done by the system.
Hence, the correct option is D.
Blood sugar, or glucose, is the main sugar found in your blood. It comes from the food you eat, and is your body's main source of energy. Your blood carries glucose to all of your body's cells to use for energy. Diabetes is a disease in which your blood sugar levels are too high. In other words, glucose provides energy for cell function.
