Temperature
... We associate the concept of temperature with how hot or cold an objects feels to the touch. Our sense of touch provides us with a qualitative indication of temperature. Our senses are unreliable for this purpose. We need a reliable and reproducible way for establishing the relative “hotness” or “col ...

The Third Law says that at 0 K a perfect crystal has no entropy. This makes sense, since an object at 0 K cannot give off heat energy (otherwise it would get co ...

First Law of Thermodynamics
... The first law of thermodynamics is the conservation of energy applied to thermal systems. Here, we develop the principles of thermodynamics for a discrete system, namely, an air parcel moving through the circulation. A thermodynamic system can transfer its internal energy by changing the temperature ...
