Front

What is temperature a measure of?

Back

The average kinetic energy of particles in a system.

Front

How is temperature typically measured?

Back

In degrees Celsius (°C) or Kelvin (K).

Front

What is the formula to convert Celsius to Kelvin?

Back

T(K) = T(°C) + 273.

Front

What does heat refer to in thermodynamics?

Back

The total energy transferred between systems due to a temperature difference.

Front

In what unit is heat measured?

Back

In joules (J).

Front

What happens when two objects at different temperatures come into contact?

Back

Energy flows from the hotter to the colder object until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

A state where the average kinetic energies of two objects are equal.

Front

What can thermal energy exchange alter in a system?

Back

It can alter internal energy, which includes both kinetic and potential energies of particles.

Front

What is latent heat?

Back

The heat absorbed or released during a phase change without temperature variation.

Front

What is internal energy?

Back

The sum of all microscopic kinetic and potential energies in a material.
