a dog can be black a ball and paint is black
The black ink absorbs most of the white light, reflecting very little back to our eyes. This absorption is what makes the ink appear black. The white paper reflects all colors of the white light, creating the contrast between the black ink and the paper.
Yes a piece of paper is an object same as a pen or an apple or a dog are objects.
the black colour absorbs all the colour and reflects nothing.this is why it appears black in colour. :) lillyXOXO
Black paper absorbs more heat because it has a darker color, which means it absorbs more light energy. Light energy is converted into heat energy when it is absorbed by an object. The dark color of black paper allows it to absorb more light across different wavelengths, resulting in more heat absorption compared to lighter-colored paper.
When light of all colors (wavelengths) is absorbed by an object, the object appears black.
Only if white space on your paper is the problem.
In general, black objects absorb all wavelengths of light, so the answer "Yes." might apply here. But it should also be noted that the answer applies to optical wavelengths (visible light) only. There is light both above (ultraviolet) and below (infrared) the visible spectrum that may or may not be absorbed by a solution or object that appears to be black to a person with normal color perception.
it should do objects absorb all light except light of the colour of the object if there is no light of that colour the object appears black

Solution of stet qusion paper 2008
Litmus paper turns blue in basic solution.
Litmus paper indicates the pH of a solution. Red litmus paper will turn blue in the presence of bases (alkaline solutions). A black color indicates that a chemical reaction is taking place with the litmus dye or paper, and this does not provide any information on pH. The paper may also turn white in the presence of strong bleaching agents such as chlorine or peroxides.

It is not true that an object will swell in an isotonic solution because there is no different concentration gradient between the object and the isotonic solution
To determine the pH of a solution using pH indicator paper, you would first dip the paper into the solution. The paper will change color based on the acidity or alkalinity of the solution. You can then compare the color of the paper to a pH color chart to determine the approximate pH level of the solution.
