Water has high heat capacity. ...
Water has high heat of vaporization. ...
Water has cohesive and adhesive properties. ...
Water is less dense as a solid than as a liquid.
properties of glass ......
The main characteristics of glass are transparency, heat resistance, pressure and breakage resistance and chemical resistance.
properties of chalk ....
Chalk, soft, fine-grained, easily pulverized, white-to-grayish variety of limestone. Chalk is composed of the shells of such minute marine organisms as foraminifera, coccoliths, and rhabdoliths. The purest varieties contain up to 99 percent calcium carbonate in the form of the mineral calcite.

FREEZING POINTS AND CRYSTALLISATION.
properties of salt
Crystals or white crystalline powder.
Transparent and colourless in crystalline form – rather like ice.
Crystallises in the isometric system, usually in the form of cubes.
Soluble in water (35.6g/100g at 0°C and 39.2g/100g at 100°).
Slightly soluble in alcohol, but insoluble in concentrated hydrochloric acid.
properties of flour
The functional properties of wheat flour and composite flours such as swelling capacity, water absorption capacity, oil absorption capacity, emulsion activity, emulsion stability, foam capacity, foam stability, gelatinization temperature, least gelation concentration and bulk density were increased with increase in the .
properties of coal
Other properties, such as hardness, grindability, ash-fusion temperature, and free-swelling index (a visual measurement of the amount of swelling that occurs when a coal sample is heated in a covered crucible), may affect coal mining and preparation, as well as the way in which a coal is used.
properties of soil
All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil's properties – its texture, structure, porosity, chemistry and colour. Soil is made up of different-sized particles. Sand particles tend to be the biggest.
properties of pen
It should feel smooth, with no dragging or scratching. Capless roller-ball pens, ballpoint, and gel pens should have a smooth mechanism for extending and retracting the writing point, and once extended the point should stay firmly in place.
properties of ink
INK PROPERTIES. There are three basic groups of ink properties: optical properties, structural properties, and drying characteristics. An ink's color is a function of the pigment used, and an ink's other optical properties are primarily determined by the pigment characteristics.
properties of soap
Soap Properties. Soaps are water soluble sodium salts of fatty acids. Soaps are made of fats and oils, or they're fatty acids, by treating them with strong alkali (a base). The making of fats and oils is the most widely used soap making process.
