What is the relationship between heat lost by one object and the heat gained by another object?

What is the relationship between heat lost by one object and the heat gained by another object?





What is the law that proves this ?What is the relationship between heat lost by one object and the heat gained by another object?
Heat is a term used to define the amount of energy an object holds. Energy defines how fast the atoms that make up an object move/vibrate. If an object is hot, its atoms vibrate much more than that of an object that is cold.





If a hot object touches a cold object, the energy from the hot object is transfered to the cold one in order to maintain an equilibrium (I know that the term is used differently in some context, but it will do here.)





Example: Water. If it's ice, then it's cold, meaning that the particles that make it up hardly move at all, which is evident by its physical properties: it's a solid. If energy is applied to it, then the particles start moving more, thus causing the ice to turn into water, which is made up of atoms that move more than that of the ice, which makes sense, as water is much more versatile. Then, if more energy is given to the water, then it will turn into gas, whose atoms move a lot more than those of the ice, and those of the water.





The law that governs this is the first Law of Thermodynamics (Also known as the law of conservation of energy), which states: ';Energy is neither created nor destroyed.'; It can change form, such as kinetic energy changing into thermal energy.
