Which part of the box type solar cooker causes greenhouse effect?
transparent glass sheet
The transparent glass sheet over the cooker is responsible for the greenhouse effect in a solar cooker. Infrared radiation emitted by sunlight is used in heating up a solar cooker. The Glass sheet is responsible for greenhouse gases because it captures the heat inside the solar cooker. Hence, the correct option is (C).
Are solar cookers good for the environment?
Solar cookers benefit the environment by: Using clean, renewable, and readily available solar energy as fuel. Preserving natural resources by not requiring the use of wood or other biomass fuels to cook. Not producing dangerous emissions which pollute local environments and contribute to climate change.
How is a solar oven similar to the greenhouse effect?
Your homemade solar oven works in much the same way as the GREENHOUSE EFFECT caused by Earth’s atmosphere. Some of this SOLAR ENERGY is reflected back into space, but some is trapped inside the box (just like the gasses in Earth’s atmosphere trap heat), causing the temperature inside to rise.
What are the advantages and disadvantages of box type solar cooker?
Advantages of Solar Cookers
- Cost-effectiveness. Unlike an LPG based cooking solution where you need to spend money every time you get a new cylinder, a solar cooker requires no such recurring payments.
- Environment Friendly.
- Nutritious, tasty and hygienic cooking.
- Power cuts is not an issue.
What is greenhouse effect in solar cooker?
There are different types and variations of solar cookers, but the basic principle of all solar cookers is that sunlight is converted to heat energy that is retained for cooking. A plastic or glass cover creates a greenhouse effect, which ensures that the retained heat does not escape.
How is greenhouse effect produced in solar cooker?
What is the science behind solar ovens?
Instead of converting solar energy to electricity, solar ovens trap light particles, called photons, to generate heat. With the help of metal reflectors, which are positioned around the oven to maximize light input, photons pass through the oven’s transparent glass top and strike the interior of the insulated box.
What is the disadvantage of solar cooker?
Disadvantages of solar cooker The solar cooker cannot be used at night and during cloudy weather. It takes more time to cook food. The direction of the solar cooker is to be changed continuously towards the direction of the Sun. Solar energy is not available uniformly all the time and at all places.
