Solar Cooking

Solar cooking is worked by means of the sun's UV rays. A solar cooker lets the UV light rays in and then converts them to longer infra red light rays that cannot escape. Infra red radiation has the right energy to make the water, fat and protein molecules iii food vibrate vigorously and heat up. It is not the sun's heat that cooks the food, nor is it the outside ambient temperature, though this can somewhat affect the rate or time required to cook, but rather it is the sun rays that are converted to heat energy that cook the food and this heat energy is then retained by the pot and the food by the means of a covering or lid.

This occurs in much the same way that a greenhouse retains heat or a car with its windows rolled up. An effective solar cooker will use the energy of the sun to heat a cooking vessel and efficiently retain the energy (heat) for maximum cooking effectiveness.

How to make a Solar Cooker

First, you would need a darkened or blackened pot with a lid. This can be a pot such as a cast iron Dutch oven, a black enameled roasting pan such as a chicken or turkey roaster or any pot that you might blacken on the outside with a non-toxic, weatherproof paint. Dark surfaces become very hot; they heat up more quickly than shiny surfaces.

Then you will need to obtain a clear transparent covering such as a large glass bowl or a durable plastic oven cooking bag. This will be used for retention of heat and will also allow the rays of the sun to be able to penetrate to the darkened cooking pot and food, thus raising the cooking temperature and preventing the heat from escaping.
Next you will need a material that will reflect extra sunlight towards the cooking apparatus so as to concentrate the sun's rays. This is usually accomplished in the form of some type of reflecting surface such as mirrors, aluminium foil and buffed tin or sheet metal. With the help of a reflecting surface, you will be able to increase the temperature and cook the food more rapidly.

Solution and Explanation

Questions 15 -18

Choose NO MORE THAN ONE WORD from the text for each answer.

A solar cooker allows the UV light rays within and after that ................. them to longer infra red light rays that cannot get away

Answer: CONVERTS
Supporting statement:“.......A solar cooker lets the UV light rays in and then converts them to longer infra red light rays that cannot escape............”
Keywords: longer, infra
Keyword Location: para 1, line 1
Explanation: it is given that a solar cooker "converts" UV light rays into longer infra-red light rays. This conversion is crucial for the cooking process as it transforms the incoming UV light into a form of energy suitable for heating up the food.

Infra red radiation has the accurate energy to compose the water, fat and protein molecules in food to pulsate and...................... heat up.

Answer: VIGOROUSLY
Supporting statement:“.......A solar cooker lets the UV light rays in and then converts them to longer infra red light rays that cannot escape. Infra red radiation has the right energy to make the water, fat and protein molecules iii food vibrate
vigorously and heat up............”
Keywords: energy, vibrate
Keyword Location: para 1, line 3
Explanation: The passage states that infra-red radiation has the "right energy" to make the molecules in food vibrate vigorously and heat up. This indicates that infra-red radiation causes the molecules to move rapidly, generating heat. The adverb "vigorously" describes the intensity of this movement.

The sun rays are ........... to heat energy that cook the food.

Answer: CONVERTED
Supporting statement:“......... but rather it is the sun rays that are converted to heat energy that cook the food and this heat energy is then retained by the pot and the food by the means of a covering or lid..........”
Keywords: energy, lid
Keyword Location: para 2, line 3
Explanation: It's not the sun's heat that directly cooks the food but rather the sun's rays are "converted" into heat energy that cooks the food. This implies a transformation of energy from sunlight to heat, which is essential for the cooking process.

A successful solar cooker will utilize the energy of the sun to heat a cooking ....... container and hold the energy (heat) for highest cooking efficacy.

Answer: EFFICIENTLY
Supporting statement:“....... An effective solar cooker will use the energy of the sun to heat a cooking vessel and efficiently retain the energy (heat) for maximum cooking effectiveness............”
Keywords: cooking, vessel
Keyword Location: para 3, line 2
Explanation: The passage emphasizes the importance of a solar cooker being able to retain the energy (heat) efficiently for maximum cooking effectiveness. This suggests that the cooker should hold the heat effectively within the cooking vessel. The adverb "efficiently" emphasizes the need for optimal utilization of the energy from the sun.

Questions 19 -21

Match each solar feature with the accurate description from the list A-E.

List of Descriptions

Heats up more quickly as compared to others.
Cook food quickly
Reflect additional sunlight in the direction of the cooking apparatus
To use less time for cooking
Used for withholding of heat

Clear transparent covering

Answer: E
Supporting statement:“.......Then you will need to obtain a clear transparent covering such as a large glass bowl or a durable plastic oven cooking bag. ...........”
Keywords: large, glass
Keyword Location: para 5, line 2
Explanation: This covering serves the purpose of retaining heat while allowing the sun's rays to penetrate to the cooking pot and food. It helps to raise the cooking temperature and prevents heat from escaping.

Dark or Black pot with a lid

Answer: A
Supporting statement:“.......First, you would need a darkened or blackened pot with a lid. This can be a pot such as a cast iron Dutch oven, a black enameled roasting pan such as a chicken or turkey roaster or any pot that you might blacken on
the outside with a non-toxic, weatherproof paint............”
Keywords: toxic, weatherproof
Keyword Location: para 4, line 3
Explanation: The passage says that using a dark or black pot with a lid for solar cooking. Dark surfaces heat up more quickly than shiny surfaces, making them suitable for absorbing and retaining heat from sunlight. The lid helps to trap the heat within the pot, aiding in the cooking process.

Mirrors, aluminum foil and buffed tin or sheet metal

Answer: C
Supporting statement:“........apparatus so as to concentrate the sun's rays. This is usually accomplished in the form of some type of reflecting surface such as mirrors, aluminium foil and buffed tin or sheet metal. With the help of a reflecting surface, you will be able to increase the temperature...........”
Keywords: aluminium, temperature
Keyword Location: para 6, line 3
Explanation: The passage given the use of materials such as mirrors, aluminum foil, and buffed tin or sheet metal to reflect extra sunlight towards the cooking apparatus. These reflective surfaces concentrate the sun's rays, increasing the temperature and speeding up the cooking process.
