Which is the physical characteristics of water?

Physical characteristics of water (temperature, colour, taste, odour and etc.) are determined by senses of touch, sight, smell and taste. For example temperature by touch, colour, floating debris, turbidity and suspended solids by sight, and taste and odour by smell.

What are 5 physical characteristics of water?

What are the physical chemical of water?

Physical properties. O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour.

What are physical and chemical characteristics?

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

What are the similarities and differences between chemical and physical properties?

Chemical property can only be observed by performing a chemical reaction. When a chemical change happens the molecular structure of a substance changes. Anything that can be measured without changing the identity or chemical composition of substance is known as the physical property of a substance.

What is the most important water quality test?

How are the physical parameters of water defined?

Physical parameters define those characteristics of water that respond to the senses of sight, touch, taste or smell. Suspended solids, turbidity, colour, taste and odour and temperature fall into this category. 1. Suspended Solids: Suspended solids in water may consist of inorganic or organic particles or of immiscible liquids (oils or greases).
