All of it in one picture
therm is one rising and falling heat. Measure it against marks and you have a thermometer; seal it in so none escapes and you have a thermos; block its way out of your feet and you have thermal socks. The box that holds heat at one level is a thermostat, and heat falling far too low is hypothermia. So when therm appears, ask whether the heat is being measured, held, or lost.
