what physical properties can be used to distinguish water from alcohol?
15061
Name two physical properties that could be used to distinguish water and ethanol. The melting point of water is 0°C with a boiling point of 100° C. Ethanol has a melting point of -117°C with a boiling point of 78° C.

These properties can be physical, chemical or biological factors. Physical properties of water quality include temperature and turbidity. Chemical characteristics involve parameters such as pH and dissolved oxygen. Biological indicators of water quality include algae and phytoplankton.

Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc.

Water is colorless and tasteless liquid. The molecules of water have extensive hydrogen bonds resulting to unusual properties in the condensed form. This also leads to high melting and boiling points.
709116
Water has some unusual properties due to its hydrogen bonds. One property is cohesion, the tendency for water molecules to stick together. The cohesive forces between water molecules are responsible for the phenomenon known as surface tension.

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. Polarity. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen.

Physical Properties: Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
