Mark (unit)

Mark (unit) refers to a standardized measurement of the amount of energy transferred from one system to another. It is defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius. The mark is used in various fields such as chemistry, physics, and engineering to express the amount of energy in a unit of mass. It is a useful tool for comparing the energy content of different substances and for calculating the energy transfer in various processes.
