Question

Match the following with reference to a solar cooker.

• A. Absorbs heat
• B. Converges heat
• C. greenhouse effect
• D. prevents heat loss

Answer 1

Solar cookers use the heat from the Sun for cooking food. The functions of different components of the solar cooker are as follows:
1. Black painted surface - The surface of the solar cooker is painted black as black absorbs maximum solar energy. This increases the temperature inside the solar cooker.
2. Concave mirror - Concave mirrors are provided in the solar cookers for concentrating solar rays over a small area. This increases the temperature inside the solar cooker.
3. Insulator - An insulator is used to insulate the cooker from outside so that the heat is not lost.
4. Glass sheet- Facilitates green-house effect as it traps greenhouse gases and radiations.
