10. Complete the map with the correct words.

ELECTRIC CARS
Powered by 1.

Features:
• energy source: 2. battery → cells with anode and cathode separated by 3. → chemical reaction releases 4. → electric 5. is powered
• 6. braking systems → recover energy when car 7.
• no fuel tanks, exhaust systems, complex 8.
• charging → standard outlet or charging stations

Advantages:
• lower 9. costs
• reduced maintenance
• 10. benefits
• quieter and smoother
• faster in 11.

Challenges:
• higher initial 12. cost
• 13. infrastructure limited in some areas
• environmental impact of battery production and 14.
11.1 Write a proper question for the following answer: Electric cars use a large lithium-ion battery as their main energy source. aperta
11.2 Write a proper question for the following answer: The two main parts are the anode and the cathode, separated by an electrolyte. aperta
11.3 Write a proper question for the following answer: When charged, chemical energy is stored in the cells of the battery. aperta
11.4 Write a proper question for the following answer: A chemical reaction releases electricity, which flows through wires to the motor, turning the wheels and moving the car. aperta
11.5 Write a proper question for the following answer: It is used to recover energy when the car slows down, which improves efficiency. aperta
11.6 Write a proper question for the following answer: Because they don’t need fuel tanks, exhaust systems, or complex gearboxes. aperta
11.7 Write a proper question for the following answer: They can be charged at home using a standard outlet or at fast-charging stations for quicker charging. aperta
11.8 Write a proper question for the following answer: They have a higher initial purchase cost and limited charging infrastructure in some areas. aperta
