Thermal Energy and Kinetic Energy Concepts

Front

What is heat?

Back

Energy transferred between two objects with varying temperatures, always moving from the warmer object to the cooler one until thermal equilibrium is reached.

Front

How does thermal energy move through a metal rod when one end is heated?

Back

Through a combination of conduction and convection.

Front

From where to where does energy transfer occur?

Back

Energy is transferred from the hotter sample to the colder sample.

Front

What happens to the temperature of soda when ice cubes are added?

Back

The heat transfers from the soda to the ice, lowering the temperature of the soda.

Front

Why does a tile floor feel cold after a hot shower?

Back

Heat from James' feet is transferred to the tile floor, making his feet feel cold.

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance, related to its temperature.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is thermal equilibrium?

Back

The state reached when two objects in contact have the same temperature and no heat flows between them.
