The sunlight passing through the glass is concentrated onto the paper thus causing the paper is burn slightly. If you gently blow onto the paper a fire will start because fires need oxygen so the oxygen that you breathed onto the paper causes the fire.

∙ 12y agoIt's actually the magnifying glass that causes the sun to burn paper by focussing the incident radiation (heat) onto a very small focal spot.

Can you burn a piece of paper using a convex lens and a bulb of 500 W?
yes, we can as we all know convex lens is a diverging lens,so,it diverges the rays of the sun .When the lens is placed over a paper,it diverges the rays,as a result of which paper burns
How can convex lens burn a piece of paper kept under it?
the lense focuses all the sun rays to 1 pint there by creating a more stronger heat ray. so it burns the paper
How will you distinguish between a convex and concave lens using a printed piece of paper?
the image formed by convex lens will converge at a point, while with a concave lens it will appear to diverge from a point.
If pieces of black paper and white paper are laid on snow in sunshine what is likely to happen?
The snow under the black paper will melt faster as the paper absorbs the heat while the white paper reflects it.
How is beta radiation used in paper making?
burns it a lot

When paper burns in a fire what is a reactant?
When paper burns in a fire, the reactants are mostly carbon (the main substance in the paper) and oxygen(from the air).
Why magnifying lens burns a paper when hold above it for longer time?
The lense is cut in such a way( usually convex ), so that the sun's rays pass through it, then refract inwards to convirge together as a point, concentrating the heat.
What is the rate at which paper burns?
5:1
What burns at 451 degrees Fahrenheit?
Paper.
What burns faster a napkin or a paper towel?
Same speed, both paper. 0,0
Can you make your sunshine yellow if its on blue paper?
with crayons or oil pastels son!
What happens to black paper when it is lane out in the snow with sunshine?
It gets very soggy
Which paper burns faster colored paper computer paper or white paper?
no, but if you but oil on it or gas that's another story
