Does water vapor block solar energy?
Yes, the denser the cloud of water vapor, the more solar energy is blocked, or more accurately "reflected" back into space.
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.
Is solar energy more efficient than electrical energy?
The two can't be compared. If you use solar energy, you'll also be using electricity - the electricity from the solar panels (unless you are talking about the other type of solar panel: the one used to directly heat water).
If solar power absorbed by solar panel's is not used does it dissipate?
two kinds of solar panel exist. if a solar thermal panel, for hot water or hot air, is not being used then any solar energy landing on it is not drawn away by the water or air. The panel temperature rises depending on the characteristics of the panel and the amount of sunshine. as the temperature rises the panel loses more and more heat back to the atmosphere so that the losses always equal the gains. energy absorbed = energy used (or stored) + energy lost.
Name 2 sources of renewable energy?
These resources include: * wood (as a material) * water (as a material) * Crops (food, fiber, meat, fish, etc.) * Solar energy (Solar electric and solar thermal) * Geothermal energy * Biomass energy (cellulose, methane) That's more than 2
Why are solar panels dark?
solar panels are in black and in dark blue color because they absorb more energy
Does a black shirt absorb more solar energy than a white shirt?
Yes it does.
What colors absorb solar energy best?
black, its a darker color so it would absorb more heat than a lighter color.
Does water vapor block solar energy?
Yes, the denser the cloud of water vapor, the more solar energy is blocked, or more accurately "reflected" back into space.
What best states how oceans and land absorb the sun's energy differently?
There are many reasons why oceans and land absorb the sun's energy differently. Land is usually darker than water so it absorbs more energy. The ocean is more reflective, and therefore uses less energy to absorb the energy.
How would greenhouse gases retain energy in the atmosphere?
Greenhouse Gases (water, carbon dioxide, methane, SF6 etc.) are made up of at least two molecules. The bond size between the atoms in the molecules is such that it can absorb heat more easily than other molecules. When solar energy comes to the atmosphere they absorb the solar energy as heat then radiate it to other atmospheric (non-greenhouse) gases such as nitrogen and oxygen..
How does a low albedo affect the earth?
A lower albedo would mean that the Earth would absorb more solar energy and warm up more.
How do water and land surfaces differ in their abilities to absorb and radiated heat energy?
Land absorbs more heat energy than water does.
Do non conventional sources of energy focus on solar energy?
"Non-conventional" refers more or less to anything that is not fossil fuels. It may be solar energy (i.e., directly capturing the solar energy), or several other types of energy - such as wind energy, water energy, and many others more.

Why do molecules in warm water absorb more sugar then the molecules in cold water?
the molecules in water have more energy and so will break down the solids quicker
What dose absorb mean?
absorb means -> you put some water on the tabel and it (absorb) ... the water is not there any more
