The first law of Thermodynamics is another way to describe the law of conservation of Energy. It states that: ​

C. The change of internal energy of a system is the sum of work and heat spent on it.

Explanation:

The law of conservation of Energy states that energy cannot be destroyed but can only be converted or transformed from one form to another. Therefore, the sum of the initial kinetic energy and potential energy is equal to the sum of the final kinetic energy and potential energy.

Mathematically, it is given by the formula;

Ki + Ui = Kf + Uf equation 1

Where;

Ki and Kf are the initial and final kinetic energy respectively.

Ui and Uf are the initial and final potential energy respectively.

The law of conservation of Energy is another way to describe the law of Thermodynamics. It states that the change of internal energy of a system is the sum of work and heat spent on it.

Mathematically, it is given by the formula;

ΔU = Q − W

Where;

ΔU represents the change in internal energy of a system.

Q represents the net heat transfer in and out of the system.

W represents the sum of work (net work) done on or by the system.

Marine life such as fish, birds, whales, dolphins and seals are affected by oil spills. Oil sticks to birds preventing them from flying. Whales and dolphins and other creatures that use blow holes can get oil into their respiratory system, making it difficult to breathe. Animals can also ingest the oil. This can become fatal in the short or long term.
