<span>The somatic nervous system is known as the voluntary nervous system, is a part of the peripheral nervous system. It consists of neurons that are associated with skeletal or striated muscle fibers. It affects voluntary signaling for many resion. A large part of the PNS is composed of 12 pairs of cranial nerves and 31 pairs of spinal nerves.</span>
<span>The first law of thermodynamics is follows the quantity dQ = dW + dU where Q is the heat flow, W is the work and U is the internal energy. Only the internal energy is a state function where it means that it does not follow a specific path to arrive at a certain number. Whereas the work and heat are not state functions and they follow a specific path or process in order to arrive at a certain number. An example would be if y</span>ou are given 2,380 J of energy to do work as 12,900 J and you are to find the internal energy. Apply the equation above:
Q = U + W
2,380 J = U + 12,900 J
U = 15,280J.
The answer would be A packing becomes less tight. The double bounds create kinks in the chain making it harder for the chains to back tightly
