Well, what is hot? It’s important to first understand, fundamentally, the concept of temperature. Wikipedia has this to say about the concept: Roughly, the temperature of a body at rest is a measure of the mean of the energy of the translational, vibrational and rotational motions of matter’s particle constituents, such as molecules, atoms, and subatomic particles. So, the temperature of an object is proportional to its internal kinetic energy. Now, let’s think about this in terms of a standard 60 watt (W) incandescent bulb – which only converts 2% of its energy into visible light. That means 98% of…
