Explanation

 Rainbows occur when sunlight is refracted, reflected, and dispersed in water droplets, creating a spectrum of colors.

When light meets a water droplet,

It is refracted at the boundary of air and water, and enters the droplet

Where the light is dispersed into the seven colors

Explanation

The universe is 13.7 billion years old with an uncertainty of 200 million years.

The WMAP model assumes that the universe's energy is made up of: 70% dark energy, 26% cold dark matter, and 4% atoms and photons

Explanation

Plasma, the liquid component of blood, is composed of approximately 90% water.

This high water content helps transport nutrients, hormones, and waste products throughout the body.

Explanation

The potential of pure water is zero.

Standard Electrochemical Potential:

The standard electrode potential of pure water is considered zero because it is the reference point against which other electrode potentials are measured.

Chemical Potential:

In thermodynamics, the chemical potential of pure water in its standard state (typically at 1 atm pressure and 25°C) is taken as a reference and thus has a relative value of zero.

Explanation
