When water is about to vaporize it is called Correct Answer saturated liquid

Explanation:

Pure substance: A substance that is made up of one kind of particle and contains a fixed or constant structure is called a pure substance.

Sub-cooled liquid: If a liquid exists at a temperature below the normal boiling temperature then it is termed a sub-cooled liquid.

Saturated liquid: The liquid which is about to vapourize for a small change in temperature is called saturated liquid.

Saturated liquid-vapor: The state at which the liquid and vapor phases coexist in equilibrium.

Saturated vapor: A vapor that is about to condense for a small decrease in temperature is called saturated vapor.

Superheated vapor: The vapor which cannot be condensed easily and the liquid will be at a temperature above the boiling temperature is called superheated vapor 
The above-mentioned regions are represented in the given P-V curve:

From the above dome G-H-D:

  • G-H = saturated liquid line
  • H-D = saturated vapor line 
  • H = critical point where saturated liquid and saturated vapor lines meet
  • The region to the left of the G-H curve is called the sub-cooled region
  • The region to the right of the H-D curve is called the super heated region 

​∴  The water which is about to vaporize is called Saturated liquid

Bottled water is drinking water (e.g., well water, distilled water, mineral water, or spring water) packaged in PET Bottle or Glass Water Bottles. Bottled water is comprehensively regulated by the U.S. Food and Drug Administration (FDA) as a packaged food product. By law, the FDA regulations for bottled water must be at least as stringent as the Environmental Protection Agency standards for tap water. What inference can be drawn from the above passage?
A three-star medicine is prepared by mixing two type of fluids (A & B) in ratio of 1 : 4. Fluid A is prepared by mixing two type of water, water M and water N in ratio of 4 : 5.

About 40 million people (over 75% are children) are affected by water borne diseases every year. Nearly six million children below 14 years of age suffer from fluorosis due to fluoride contamination in water. Arsenic is another dangerous contaminant in ground water, putting at risk more than 10 million people in the country. Bacteriological contamination, which leads to diarrhea, cholera, hepatitis etc., is at alert level in India. Contamination due to Iron, hardness and salinity in water are other major concern. Medical expenditure on water borne diseases is estimated to be Rs. 2400 crores annually in the country. The need for desalination and water purification is destined to grow in the coming years as the requirement for water increases. Bhabha Atomic Research Centre (BARC) has been engaged in R&D on desalination and water purification technologies for several years and has developed indigenous technologies which are available for know-how transfer to interested parties The given information, if accurate, most accurately supports which statement?
