Different Laws of energy and gas

1st Law of thermodynamics is energy cannot be created or destroyed, but can be converted from one form to another. When one form is generated it is done at the expense of another energy form.

2nd Law of theemodynamics is energy tends to degrade into low-level heat energy. In order for heat energy to travel there has to be a temperature difference between the materials. Heat can never be completely converted into other forms of energy, but other forms of energy can completely converted into heat energy. Heat always travels to a cooler temperature.

Boyle's Law- there is a definite relationship between the pressure and volume of a gas if the temperature is kept constant. Pressure and volume of gas are inversly related, this means that if the volume is decreased, the pressure will increase and if the volume is increased the pressure will decrease.

Charle's Law- there is a definite relationship between the volume and the temperature of a gas if the pressure is kept constant. Also states that there is a direct relationship between the pressure and temperature of a gas, if volume is kept constant.

Dalton's Law- the total pressure of a confined mixture of different gases is equal to the sum of the pressures of each gas in the mixture.

General Law of Perfect Gases- relates volume, pressure and temperature.

If your interested in the HVAC (heating, ventilation, and air conditioning) this is some basic knowledge you will have to know. Or of course any science etc. that would relate to this.
