At least a 20 Volume, 6% peroxide should be used for lifting.

Although, the hair tone can still be changed with 10 Volume, 3%. Using this however, you will not see much lift.

What is the differnece between precepitation formed in physical change and chemical chnge?

In a physical change, precipitation is formed when solubility limits are exceeded and a solid substance forms out of a solution, not involving a change in the chemical makeup of the substances involved. In a chemical change, precipitation occurs when two or more substances react chemically to form a new substance that is insoluble and separates from the solution.


How does the position of the sun chnge in the sky with the change of seasons?

The Earth orbits around the Sun. The orbit is elliptical - all orbits are - but the "eccentricity" of the orbit is pretty small. That means, it's only a little different from a circle. The path of the Earth around the Sun doesn't really contribute to the seasons. The Earth spins like a gyroscope, and like a gyro, it is VERY stable. But the gyro is tilted, and it STAYS tilted. The "tilt angle" isn't great; it is approximately 23.5 degrees. It is this tilt, which we call "axial tilt", that causes the seasons.
