Energy Transformations

Front

What is energy transformation?

Back

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

Front

What are the main types of energy?

Back

The main types of energy include kinetic, potential, thermal, chemical, electrical, and nuclear energy.

What energy transformation occurs in a battery-operated device?

Back

Chemical energy is transformed into electrical energy, which is then transformed into other forms of energy, such as sound or light.

Front

What happens to energy in a microwave oven?

Back

In a microwave oven, electrical energy is transformed into thermal energy to heat food.

Front

What is an example of chemical to mechanical energy transformation?

Back

An example is a car engine, where chemical energy from gasoline is transformed into mechanical energy to move the car.

Front

What type of energy transformation occurs in a fan?

Back

A fan transforms electrical energy into mechanical energy to create airflow.

Front

What is the role of conduction in energy transformation?

Back

Conduction is the process of heat transfer through direct contact, which can lead to energy transformation, but it does not create energy.

Front

What energy transformation occurs when you turn on a light bulb?

Back

Electrical energy is transformed into light energy and thermal energy.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (like solar and wind), while non-renewable sources (like coal and oil) cannot be replaced once used.

What is an example of energy transformation in photosynthesis?

Back

In photosynthesis, light energy is transformed into chemical energy stored in glucose.
