How does the solar heater heats up the water in the tank?
The solar panels absorb energy from then sun, the solar energy is then transformed into heat energy causing the water to heat up.
Does the land area or water area of Earth's surface absorb more solar energy?
Short Answer:Since there is so much more water than land, one expects that most of the solar energy absorbed by Earth is absorbed into the oceans. That is correct.Crudely, twice as much energy is absorbed by the oceans as the land since there is roughly a bit more than twice as much ocean as land.More Technical (Albedo):The characterization of how much solar energy is absorbed by a portion of the surface of the Earth is something called the albedo of the surface. Some surfaces, like dirt, forests and the ocean absorb most of the Sun's energy. Others, like Snow reflect most of it. Deserts are in between.The albedo of a surface is the fraction of light it reflects. (The term "reflects" does not mean like a mirror but rather means scatters or causes to light bounce back to distinguish "reflection" from the process where light is absorbed.) Normally, one refers to sunlight when quoting an albedo, but if a different or specific wavelength range is being considered, there are different values of the albedo that are defined for different parts of the electromagnetic spectrum.On average, the ocean surface has a low albedo meaning it absorbs most of the light that gets to it.The same is true for bare soil and most forests.Though the albedo is variable, 70 or 80 % of the light is absorbed.Desert areas typically have high albedos and can reflect most of the light.Most land areas are in an albedo range of 0.1 to 0.4, so 90% to 60% of the light is absorbed.The average albedo of the Earth is about 0.3, somewhat higher than typical of oceans or much of the land area primarily because of the contribution of clouds.Clouds reflect light very effectively, absorbing little.
Why the solar cookers are painted inside as well as outside?
Because if we will not paint then the heat is reflect on the solar cooker
How is solar energy captured?
Solar energy is captured and converted to normal energy through solar panels.You see the solar panle collects the energy from the sun some solar panels turn the heat into energy but others collect it from the light. The energy goes in an energy box and when energy is needed the energy that the solar panel collected gets used.It only transforms, it is not yet possible to make energy.I've given a couple links below to articles that can answer your question.
What changes can solar energy cause to a person lying in the sun?
Solar energy is not heat
Why is solar energy attracted to black objects?
Solar energy is not attracted to black objects. Black objects just absorb light rather than reflect it.
Name the pigment which can absorb solar energy?
Chloroplasts the pigment which can absorb solar energy.
What are three things that absorb and reflect solar energy and keep the earth balanced?
Clouds reflect 20% and absorb 4% of incoming solar energy.The atmosphere (water drops, dust and ozone) absorbs 16%.The surface of the earth (land, vegetation, water and ice) reflects 4% and absorbs 50%.
Does white plastic absorb or transmit solar radiation?
White anything will REFLECT radiation, it will not transmit or absorb.
Can solar panels absorb infrared rays?
parts in the solar panel will absorb infra red reflect and let through infra red. the copper plate painted black will absorb.
Which molecules are essentially required to absorb solar energy to carry out photosynthesis?
Which molecules are essentially required to absorb solar energy to carry out photosynthesis?
Why would painting rooftops white help save the planet?
I suppose it would reflect solar energy back into space rather than absorb it on earth
Is evaporation affected by solar energy?
Yes, in fact solar energy is the cause of evaporation from the oceans
How do solar panels absorb energy?
mere
What is Best surface to minimize solar heat gain?
The answer lies in the Leslie Cube (look it up in an Internet search). Though the cube demonstrates which surface radiates heat better the principle is the same. A dark colour absorbs solar energy better than a light surface and a matt surface likewise absorbs solar energy better than a gloss surface. Think of it this way ... the amount of solar energy hitting two side by side surfaces is the same for each but the light glossy one will reflect more solar energy and therefore absorb less while the dark matt surface will reflect less solar energy and therefore absorb more. Hence solar heat collectors are black.
What is an example of energy being transferred?
when solar energy gets away from the sun and the plants absorb the solar energy.
Does the color red take in solar energy?
Red-coloured objects appear red because they reflect mostly red light. Thus, they must absorb most of the other colours of light. Since light carries energy, they are absorbing solar energy, which is, of course, why objects that are left in the sun get hot. Objects that are coloured black absorb all visible frequencies (colours) of light, which makes them appear dark, and also means they will absorb the most solar energy and heat up fastest in the sun.
