in this Lesson:
Second: The high specific heat of water
Internal energy
Any system or body consists of an enormous number of molecules that are being in a continuous

motion. Therefore, it has:


A system: is a definite portion of the physical universe chosen for studying and characterizing.

Temperature: It is a quantitative description of how hot or cold a body or a system is, or a measure of the average kinetic energy of the molecules of a body or a system.

Amount of heat: It is the thermal energy that is transferred from, to, or through a body when there is a difference in temperature.

Specific heat: The amount of heat required to raise the temperature of 1 kg of a substance by one degree Celsius or one kelvin..

Third: The high latent heat of vaporization of water
