First Law of Thermodynamics

First Law of Thermodynamics

Short Description of Topic

The Main Idea

The First law of Thermodynamics states that energy can be neither created nor destroyed. It is also known as the conservation of energy. Even if the energy cannot be created or destroyed, power generation process and energy sources help the conversion of the energy from one form to an another.

A Mathematical Model

{∆U = Q-W} where F U is change in the internal energy ,Q is heat added to the system, and W is the work done by the system.

A Computational Model

Examples

Energy Transformation

By the photo, there is no energy made or destroyed. From eating a piece of chicken that has chemical energy will transform into kinetic energy when riding the bicycle. Also with the light energy of the sun will transform into chemical energy of the plant's leaf. This is an expample of energy transformation.

Connectedness

1. How is this topic connected to something that you are interested in?

This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school.

1. How is it connected to your major?

As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics

1. Is there an interesting industrial application? To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.

1. Is there an interesting industrial application?

There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out.
