Number of times to move the spoon

Rule change at this point from a solid to a liquid state
Note
: The first law of thermodynamics text of the first law of thermodynamics: the change in thermal energy thermal conductivity chart Δ U to an object is equal to the amount of the amount of heat Q added to the body minus the workpiece W which his body. Δ U = Q - W examples to change the amount of thermal energy in the system: the hand pump used in the framework of inflatable bicycle examples of the transformation of forms of energy thermal conductivity chart into thermal energy: 1 transformation of electrical energy into heat: Toaster - 2 electric furnace turning light energy into thermal energy: the sun's rays heat engines .. thermal machine: thermal conductivity chart it is a tool with the ability to convert thermal energy into mechanical energy on an ongoing basis ... as a result of heat transfer to the device from the heat source with a high temperature and expel the heat to a thermal reservoir degrees low heat.
Δ U = Q - W = 0
Coolers (refrigerators) ..
Extracted thermal conductivity chart the pump in the summer heat of the house and so cool ..
ΔS = Q / T
