Understanding Temperature

Front

What is temperature a measure of?

Back

Temperature is a measure of the average kinetic energy of the particles within a substance.

Front

How does heat transfer between objects of different temperatures?

Back

Heat transfers from the object with a higher temperature to the object with a lower temperature until thermal equilibrium is reached.

Front

What instrument is commonly used to measure temperature?

Back

A thermometer is commonly used to measure temperature.

Front

What is the SI unit of temperature?

Back

The SI unit of temperature is the kelvin (K).

Front

What is absolute zero?

Back

Absolute zero is the lowest possible temperature, at which particles have minimal thermal motion. It is 0 K or -273.15°C.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat between them because they are at the same temperature.

Front

What is the Celsius scale based on?

Back

The Celsius scale is based on the freezing point (0°C) and boiling point (100°C) of water at standard atmospheric pressure.
