Physics 312 Lecture: "Heat as Energy and Specific Heat Capacity." May 1, 1998

The ideal gas law can be expressed in a form which contains the number of molecules of gas N, rather than number of moles n:
```
              P * V = N * k * T
```
where k is Boltzmann's constant.
Heat is a form of energy, like kinetic energy and gravitational potential energy; one may convert energy from heat to other forms, and vice versa
The calorie is a unit of energy often used in heat problems; 1 calorie = 4.186 J.
One thousand calories, or one kilocalorie, is the "food calorie" found in diet information
When one adds heat to an object, its temperature rises. The ratio of the increase in an object's temperature to the amount of energy added, and its mass, is called its specific heat capacity.
