🔑 The first law of thermodynamics relates the change in internal energy to the heat and work done on the gas.
🌡️ Heat is related to the temperature change, while work is related to the change in volume.
📚 The second law of thermodynamics states that the overall entropy of a closed system always increases.
🔥 When heat is added to a gas, it can increase in temperature or volume and perform work.
💡 The second law of thermodynamics states that processes are typically irreversible, meaning they cannot return to their initial state.
⚖️ While the conservation of energy holds true, practical processes in everyday life are mostly irreversible.
🔥 The second law of thermodynamics states that the temperature inside a nucleus increases due to agitation caused by heating.
🍿 Popcorn does not revert back to corn kernels once it has been heated because the process is irreversible.
⚡️ The second law of thermodynamics states that all processes have an efficiency below 100% and most processes are irreversible.
🔑 Processes have efficiency below 100%, which is a consequence of the second law of thermodynamics.
🔑 Heat can only flow spontaneously from a higher temperature to a lower temperature.
🔑 Cooling systems like air conditioners transfer heat from a lower temperature to a higher temperature by expending energy.
🔑 The second law of thermodynamics states that heat flows spontaneously from a higher temperature body to a lower temperature body, with a loss in efficiency.
💡 This law applies to both heat engines and refrigerators.
