Limestone, iron, dissolved minerals and sediment found in soil can contribute to hard water. If water passes over these minerals on its journey to your home, it can create hardness in your water. The surrounding environment can play a large part in the quality of your water. Other factors t...
1. Definition of Temporary Hardness: Temporary hardness in water refers to the hardness that can be removed by boiling. It is primarily caused by the presence of certain compounds in the water. 2. Identification of Compounds: The main causes of temporary hardness are the presence of calcium bic...

On the other hand, hard pertains to the physical hardness of materials, the level of difficulty encountered in tasks or situations, or the intensity of effort required to achieve something. Hard can describe tangible attributes, such as the hardness of a diamond, or abstract concepts, such as ...
In terms of measurement, the hardness of a material is often scientifically quantified using scales such as the Mohs scale of mineral hardness or the Brinell hardness test. Solids, however, are categorized more broadly based on their physical state rather than measurable scales of hardness. 5 ADVE...
