Thermometry: measuring temperature.

'''Q1: What is temperature? Just a number?'''
:A1 - the degree or intensity of heat present in a substance.
:A2 - a measurement of the average kinetic energy of a particle in a system; 3/2kT <--per molecule

'''Q2: How do we measure temperature?'''
:A1 - Most commonly we use a thermometer.
