"Specific heat is the amount of heat required to raise one gram of any substance one degree Celsius or Kelvin. The formula for specific heat is the amount of heat absorbed or released = mass x specifi ...
"Entropy measures the amount of disorder in a system. Nature tends towards disorder, so as time elapses, entropy naturally increases. Energy is required in order to decrease entropy." Fuente: BrightSt ...
"Enthalpy is the heat content of a system at constant pressure, but chemists almost always talk about change in enthalpy rather than total energy. Endothermic reactions have positive changes in enthal ...
"The Second Law of Thermodynamics can be rephrased in several ways. Fundamentally, it says that heat always flows from hot objects to cold objects (unless work is exerted to make it flow the other dir ...
"Conservation of energy, sometimes called the first law of thermodynamics, states that energy can neither be created nor destroyed. Energy, however, can be transferred from one form to another." Fuent ...
