Q:

What is the relationship between absorbance and concentration?

A:

There is a direct relationship between absorbance and concentration is the higher the absorbance of a substance, the more concentrated its solution will be in water or another medium. In chemistry, this is a principle known as the Beer-Lambert Law.

The law measures the absorbance of a substance in a medium by determining how well light passes through it. The more heavily concentrated the substance, the less visible light passes through. The law also states that when judging the penetration of light using a spectrometer, fewer wavelengths of light, both visible and invisible, can pass through as the concentration of the substance increased.

    How does invisible ink work?

    A:

    Invisible ink is a solution or compound that becomes visible upon addition of another substance and can either be made through a chemical or physical process. For example, certain "invisible" solutions only require UV light to become visible, while others require the addition of specific chemicals to set up a reaction.

    What is mutualism in a grassland biome?

    A:

    Examples of mutualism in grassland biomes include the relationship between plant roots and their symbiotic fungi, as well as the relationships between termites and the protozoans that live in their digestive tracts. Regardless of what ecosystem it takes place in, mutualism is the interaction between two different species that benefits both organisms. It differs from other inter-species relationships, such as predation or parasitism.

  • Q:

    Is there a relationship between viscosity and density?

    A:

    There is no relationship between the viscosity and density of a fluid. While viscosity is the thickness or thinness of a fluid, density refers to the space between its particles. However, both properties are affected by temperature. When a fluid is heated, its particles move far apart, and it also becomes less viscous.
