S2 E10 • Mesure de la température

Given three bathtubs of varying temperature, the star of the show ""blunts"" his feet so that they can't tell temperature. Sure they can't. The human body can only tell changes in temperature in comparison to what it had been used to. It's up to an independent device: a thermometer and the scale devised by Anders Celsius.

S2 E11 • La différence entre la température et la chaleur

What is better to warm up a kiddie pool: a teacup of boiling water (100° Celsius) or a bucket of water at 50° Celsius? The answer tells you the difference between temperature and heat.

S2 E12 • Les atomes

There's more to matter than the molecules we had spent discussing in the previous six shows. This fourth unit produces that first look at atoms.

S2 E13 • Les électrons

An atom is made of mostly empty space. The electrons in an atom zoom around at fantastic speeds to create existence out of something that is mostly nothingness (at the atomic level).

S2 E14 • La conduction

All objects conduct heat, of course, but get a look at objects from the atomic level and you'll see why some objects conduct heat faster than others.

S2 E15 • Le volume et la masse volumique

To set up audiences for The Convection of Heat, this question is posed: how can you fit eight junky cars into a small space?

S2 E16 • La flottabilité

How come an anchor is easier to lift if it's in the water than in open air? It lies in the density of an object versus a certain quantity of water.

S2 E17 • La convection

Now that the Principle of Buoyancy is understood, one can fully grasp The Convection of Heat. This is demonstrated with a furnace not being in the attic of a house.

S2 E18 • Chaleur en tant qu'énergie

An animated Count Rumford demonstrates, for the first time, how heat can be used to produce energy. The show converts a Calorie as the amount produced from 4200 joules of work.

S2 E19 • Les ondes de la radiation

Why does somebody stand in the shade on a hot day? This show introduces the third method by which heat can be transferred: radiation.

S2 E20 • Le spectre de la radiation

Is it just your imagination that you are warmer when you wear dark clothes over white clothes? That actually sets off a reveliation on what color really is.
