Temperature

Front

What is the definition of temperature?

Back

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

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the particles in a substance also increases.

Front

What are the three main temperature scales?

Back

The three main temperature scales are Celsius, Fahrenheit, and Kelvin.

Front

At what temperature does water freeze on the Celsius scale?

Back

Water freezes at 0 degrees Celsius.

Front

At what temperature does water boil on the Celsius scale?

Back

Water boils at 100 degrees Celsius.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which all molecular motion stops, defined as 0 Kelvin or -273.15 degrees Celsius.

Front

What are good conductors of heat?

Back

Good conductors of heat are usually solid metals, such as copper and aluminum.

Front

What is the effect of altitude on boiling point?

Back

At higher altitudes, the boiling point of water decreases due to lower atmospheric pressure.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

How does temperature affect the state of matter?

Back

Temperature changes can cause matter to change states, such as from solid to liquid (melting) or from liquid to gas (evaporation).
