Temperature

What is thermal equilibrium?

Heat can enter or leave a system through a boundary. Any two systems that are in contact with one another, with no flow of heat between them, must be in thermal equilibrium and thus have the same temperature.

How do you convert from Celsius to Kelvin?

Add 273.15

Why is the absolute scale used?

It doesn’t arbitrarily depend on the properties of a given substance

disadvantages of thermistors

non linear response, fragile, high resistance, can be loud

advantages of thermistors.

small, high sensitivity, cheap, quick response.

advantages of thermocouple thermometers.

wide temperature range, quick response, cheap.

disadvantages of thermocouple thermometers.

hard to recalibrate.

In which direction is heat energy transferred?

From hot regions to cooler regions.
