Thermal Energy

Front

What happens to the temperatures of two connected rooms when one is warmer than the other?

Back

The temperature of the warmer room will lower and the temperature of the cooler room will rise until they reach equilibrium.

Front

What instrument is used to measure temperature?

Back

Thermometer.

Front

What is condensation?

Back

Condensation is the process where water vapor in the air cools and changes into liquid water, often seen as droplets on cold surfaces.

Front

Describe the heat transfer that occurs when a cold object is placed on a warm surface.

Back

Heat is transferred from the warm surface to the cold object, increasing the temperature of the cold object.

Front

What is the role of an insulator?

Back

An insulator slows down the transfer of heat, helping to maintain the temperature of an object.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.

Front

What happens to the temperature of an object when it absorbs heat?

Back

The temperature of the object increases.

Front

What is equilibrium in terms of temperature?

Back

Equilibrium is the state where two objects in contact reach the same temperature and no heat transfer occurs.

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into vapor, usually occurring at the surface of the liquid.
