Matter and Energy Concepts

Front

Conservation principle in energy

Back

Energy can neither be created nor destroyed.

Front

Complex compounds

Back

Complex compounds cannot change state.

Front

Energy Loss in Combustion

Back

Combustion creates heat, which is lost to the surroundings.

Front

Energy in Falling Objects

Back

Kinetic energy is exemplified by an object as it falls.

Front

Heat as an Energy Source

Back

Heat from sunlight can be used to create electricity

Front

Dispersed energy

Back

Has high entropy due to increased disorder.

Front

Low Quality Energy

Back

Dispersed at low temperatures and difficult to gather, making it costly to use.

Front

Passive solar heating relies on natural convection for air movement.

Back

This process is essential for distributing warm air throughout the space.

Front

Building orientation is important for maximizing sunlight exposure in passive solar heating.

Back

Proper orientation ensures optimal solar gain throughout the day.

Front

Thermal infrared emissions

Back

Not visible to the human eye, unlike visible light.
