Suppose Q represents the heat exchanged between a system and the environment, and W is the work done by or on the system.
We will see in this chapter how internal energy, heat, and work all play a role in the first law of thermodynamics.
His humorous statement of the first law of thermodynamics is stated “you can’t win,” or in other words, you cannot get more energy out of a system than you put into it. Snow (1905–1980) is credited with a joke about the four laws of thermodynamics. This interaction is given by the first law of thermodynamics. Now that we have seen how to calculate internal energy, heat, and work done for a thermodynamic system undergoing change during some process, we can see how these quantities interact to affect the amount of change that can occur. Explain how heat transfer, work done, and internal energy change are related in any thermodynamic process.State the first law of thermodynamics and explain how it is applied.By the end of this section, you will be able to:
