Part VIII IN WHICH we learn the basics of Temperature. Up until now all the quantities we have discussed could be broken down into measurements of mass, distance, and time. For example, POWER is measured in Watts, but Watts = J/s = Nm/s = (kgm/s^2)m/s = kgm^2/s^3 So power can be expressed in terms of mass (kg), distance (m), and time (s). Now we learn about a completely new quantity – temperature. This begins our study of Thermodynamics – the physics of temperature and heat.
