# Thermodynamics

### Science  Education!

Thermodynamics is the branch of physics that has to do  with the relationships between heat and other types of energy. it tells you how thermal energy is changed to and from other types of energy and how it has to do with matter.

# HEAT

Thermodynamics, then, is concerned with several properties of matter; mostly  among these is heat. Heat is energy moving  between substances or systems because of  a temperature difference between them, according to Energy Education Heat.

# Temperature

The amount of heat transferred by something depends on the speed and number of atoms or molecules moving according to Energy Education. The faster the atoms or molecules are moveing, the higher the temperature, and the more atoms or molecules that are moving, the greater the amount of heat they make or in other words transfer.

# Thermal conductivity

Thermal conductivity  is “the rate of heat that passes through different things,  the amount of heat that moves, or in other words flows through each  thing or in other words unit. a unit area with a temperature the same as one type of unit distance.

# Newtons law of cooling.

In 1701 newton first started his law of cooling. in a short article named Scala graduum, caloris. ( a scale of the degrees of heat), in the royal society. the statement that newton had said,  gave the law the original Latin. And that is the newton law of cooling.

# Heat transfer.

Heat can be transferred from one body to another body or even  between a body and the environment by three different means: conduction, convection and radiation.:) conduction is a transfer of energy, that goes through something hard or like something that is solid. conduction between bodies only happens when they are close together.

# Entropy.

Thermodynamic systems make waste heat. the waste always come down to higher entropy. Entropy always increases  and gets higher, it never gets lower because if it moves apart it will make waste heat. mostly from making heat it leaks from the system.
