What are D properties of water?
Water is a liquid at standard temperature and pressure (25 degrees Celsius and 1 atm, for liquids). Water is is tasteless and odorless. Water is transparent in the visible part of the electromagnetic spectrum. Water can act as either an acid or a base.
What are 3 properties of water that are important to life?
Water is essential for all living things. Water’s unique density, high specific heat, cohesion, adhesion, and solvent abilities allow it to support life.
What is the best property of water?
Unique properties of water
- Water is polar.
- Water is an excellent solvent.
- 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.
What are the different properties of water that is important to life?
Water is the medium of life. Its four key properties – thermal properties, ability to act as a universal solvent, cohesion and adhesion – help support the life processes and habitats of virtually all organisms.
What is the importance of properties of water?
Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients.
What properties of water give it a unique role in the environment?
Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
What is the viscosity and temperature of water?
Water Properties – 1000 psia (68.1 atm) Temperature [°F] Density [lb m /ft 3] Viscosity [10 -7 lb f sec/ft 2] 70 62.50 204 80 62.42 177 90 62.31 160 100 62.19 142
How are the properties of water different from other liquids?
The molecules of water have extensive hydrogen bonds resulting in unusual properties in the condensed form. This also leads to high melting and boiling points. As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole moment, etc.
How is Vd used to calculate maintenance doses?
Vd is used to calculate loading doses, much as clearance is used to calculate maintenance dose. It can be expressed as litres, or indexed to body mass in L/kg. Plasma concentration can be observed at different times, giving rise to several different possible strategies of calculating the volume of distribution.
Which is a major physiological determinant of VD?
The drug factors would include tissue binding, plasma protein binding and physicochemical properties of drug (size, charge, pKa, lipid solubility, water solubility).” Birkett (2009) at the end of Chapter 2 lists protein and tissue binding as the “major physiological determinant” of Vd.
