effect of change of colour on matter

The temperature effect on heating a solid varies depending on the nature of the solid and the conditions required in bringing the change..

When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperature at which it melts under one atmospheric pressure. Increase in pressures usu..

">The phenomenon by which, a ray of light splits into its constituent colours, when passed through a transparent medium, is known as dispersion. The band of colours obtained due to the dispersion of light is called the spectrum. Atmospheric Refraction Atmospheric refraction is t..

Summary Matter is anything that occupies space and has mass Element is a pure substance, which can neither be decomposed nor built from simpler substances by any physical or chemical means. It contains only one kind of atom. Broadly speaking, elements can be divided into metals..

Effect of Pressure on Matter - Pressure has little effect on the state of solids and liquids as the inter-particle distance is already minimized in these situations. However, the effect of pressure in case of gases is considerabl..

Is Matter Around us Pure - Physical and Chemical Changes Matter undergoes certain changes as a result of the application of energy. Water from saltpans on the seacoast dry up, leaving behind salt; water from the sea evaporates to from water vapour, which conv..

In order to undo the effect of the change, equilibrium shifts in the forward direction producing colorless solution. Addition of dilute sulphuric acid solution restores the reddish brown color indicating that the equilibrium has shifted to the left. The acid increases the concen..
