Temperature
Summary
Temperature is the measure of the average kinetic energy of the particles in a substance, which is related to how hot or cold that substance is.Historically, two equivalent concepts of temperature have developed, the thermodynamic description and a microscopic explanation based on statistical physics. Since thermodynamics deals entirely with macroscopic measurements, the thermodynamic definition of temperature, first stated by Lord Kelvin, is stated entirely in empirical, measurable variables. Statistical physics provides a deeper understanding of thermodynamics by describing matter as a collection of a large number of particles, and derives thermodynamic (i.e. macroscopic) parameters as statistical averages of the microscopic parameters of the particles.In statistical physics, it is shown that the thermodynamic definition of temperature can be interpreted as a measure of the average energy in each degree of freedom of the particles in the thermodynamic system.

The Morning Call Revisits Amazon's Work Conditions
Remember that Morning Call investigation a couple of months ago into an Amazon sweatshop outside Allentown, Pennsylvania? The paper showed that the company endangered temp employees in a warehouse where temperatures sometimes hit 110 degrees all while issuing difficult-or-impossible-to-meet productivity standards in order to keep from hiring them full time. It turns out Amazon's climate-control problem was year-round.
