You pop a muffin in the microwave. You wrap your cold hands around a steaming mug of soup.

Physics Narrative 11-14

What is the relationship between the amount of energy in the thermal store of a warm object and the temperature of that object...

Physics Narrative 11-14

Let's think about conduction in solids first. Here each particle vibrates but ends up going nowhere over the longer term. This...

Physics Narrative 11-14

Radiation is quite different from both convection and conduction. Consider the case of warming by the Sun on a bright summer's...
