24-25 Energy Study Guide #6-10

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

What is the process of energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy to kinetic energy.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat energy through electromagnetic waves, such as sunlight warming the Earth.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

How does the sun's energy affect ocean water temperature?

Back

The sun's energy warms the surface of the ocean, making it warmer than the deeper water, which absorbs less sunlight.

Front

What is the main reason for temperature differences in ocean water?

Back

The main reason is that water at the surface absorbs more energy from the sun compared to water at the bottom.

Front

What is an example of energy transformation in a bicycle ride?

Back

When a bicycle rider eats breakfast, the chemical energy from the food is transformed into kinetic energy as they ride.

Front

What is the role of heat energy in a closed system?

Back

In a closed system, heat energy can build up over time, affecting the temperature and energy transfer within the system.
