Heat capacity measures the amount of energy needed to raise a body's temperature by one degree. Finding the heat capacity of a material is reduced to a simple formula: just divide the heat exchanged between the body and the environment by the temperature difference, so as to obtain the energy per degree.

The Kelvin measurement scale is a thermodynamic scale where zero indicates the point at which the molecules do not emit heat and are completely immobile. To be able to convert a measurement expressed in Kelvin to one expressed in Fahrenheit or Celsius, you can use the steps shown in this guide.

Transformers are electrical components that connect at least two circuits together, allowing the passage of energy. Their function is to regulate the voltage of the circuits themselves, but in certain cases they can be damaged and prevent the operation of the devices connected to them.
