The water bath provides heat, which speeds up the reaction.
during the water bath a color change will occur to signify the presence of glucose. from light blue (no glucosepresent) to green. yellow, orange, red.
The water must be heated to 95oc to speed up the reaction.
The recommended temperature is 95 oC.

Yes, reaction won't go at room temperature.

You don't use it in your bath water.
Yes, as the water in the beaker will finally get the same water temperature in the water bath.

usage of bath
To test for the presence of monosaccharides and reducing disaccharide sugars in food, the food sample is dissolved in water, and a small amount of Benedict's reagent is added. During a water bath, which is usually 4-moiety, after isomerization.Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose isomerizing to aldehyde, or the fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent. Sucrose indirectly produces a positive result with Benedict's reagent if heated with dilute hydrochloric acid prior to the test, although after this treatment it is no longer sucrose. The acidic conditions and heat break the glycosidic bond in sucrose through hydrolysis. The products of sucrose decomposition are glucose and fructose, both of which can be detected by Benedict's reagent, as described above.Starches do not react or react very poorly with Benedict's reagent, due to the relatively small number of reducing sugar moieties, which occur only at the ends of carbohydratechains. Inositol (myo-inositol) is another carbohydrate which produces a negative test.Benedict's reagent can be used to test for the presence of glucose in urine. Glucose found to be present in urine is an indication of diabetes mellitus. Once a reducing sugar is detected in urine, further tests have to be undergone in order to ascertain which sugar is present. Only glucose is indicative of diabetes.
A water bath is a bath of vigouriously boiling water
A hot water bath is a bath with hot water. You use it to take a bath.
the energy that a bath of hot water is thermal energy because the bath water ransfers to you to make you warmer and the bath water colder.
water bath
A kettle of water typically reaches a higher temperature than bath water, as kettles are designed to heat water quickly. The water in a bath is usually at a comfortable temperature for bathing, which is lower than the boiling point of water in a kettle.
Desolve 2g of sodiume acetate in 20ml water and place in a round bottom flask. Add 2g phenyl hdrazine hydrochloride in it. Dissolve 1g glucose in 5ml water and addit to the above flask. Heat the flask on water bath for 1 hour. separate the yellow crystals by filtration and wash with acetic acid. GLUCOSE + 3PHENHYL HYDRAZINE HYDROCHLORIDE------->PHENYLE GLUCOSAZONE
That is because of water displacement.
