Buffer solution
They are those solutions which has a constant value of pH , no matter what we add in to them .
Example: The pH of Blood is 7.4-7.6. Blood act as a buffer. As u all know, in spite of eating so many types of food items, the pH of blood remains same.
The buffer solution is defined as: A solution which resists the change in hydrogen ion concentration on addition of a small amount of acid or a base in to it.

Moisture present in the atmosphere in the form of gaseous state is called water vapour.Humidity is the amount of water vapour present in the atmosphere.
1. There is a variation in the content of water vapour in the atmosphere with respect to time and place.
2. As one goes higher in the altitude, the amount of water vapour decreases. Above twelve km from the earth's surface, there is almost no water vapour.
3. In polar regions it is practically absent in winter while in warm and humid equatorial regions have a high amount of water vapour.
4. Water vapour is the source of moisture for clouds, rain and frost.
5. Water vapour is the gas that absorbs heat. Hence, it is so a greenhouse gas. It releases this heat when it condenses.
6. It plays a prominent role in heating and cooling of the atmosphere.

Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth. In order, the most abundant greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), chlorofluorocarbons (CFCs).

(3-4×4+6÷2)+3-7-5×4
= (3-4×4+3)+3-7-5×4
= (3-16+3)+3-7-5×4
= (6-16 )+3-7-5×4
= (-10 )+3-7-5×4
= (-10 )+3-7-20
= -10+3-27
= - 37 + 3
= -34

- Ions bound together by electrostatic attraction form ionic crystals. Their arrangement varies depending on the ions’ sizes or the radius ratio (the ratio of the radii of the positive to the negative ion). A simple cubic crystal lattice has ions equally spaced in 3D at 90° angles.
- Stability of ionic solids depends on lattice energy, which is released in the form of heat when two ions are brought together to form a solid. Lattice energy is the sum of all the interactions within the crystal.
- The properties of ionic crystals reflect the strong interactions that exist between the ions. They are very poor conductors of electricity, have strong absorption of infrared radiation, and are easily cleaved. These solids tend to be quite hard and have high melting points.

The retouching tools in Adobe Photoshop are: Clone Stamp, Pattern Stamp, Healing Brush, Patch and Color Replacement. This tool repairs a selected area with pixels that can be taken from another area or a pattern. There is quite a similarity between the Healing Brush Tool and the the Patch Tool since it also matches the texture, lighting, and shading of the sampled pixels to the source pixels.
