FOOD TEST

1. To test presence of glucose:
Glucose solution + Benedict's solution, then heated in the water bath

Glucose + Benedict's solution before being heated

2. To test presence of protien
Albumen solution (protein) + Millon's reagent, then heated in the water bath

Albumen + Millon's reagent before being heated

Mixture of Glucose+ Benedict's and albumen+Millon's are heated

CONVECTION

Hot water (less dense) eises to the top while the cold water (denser) descends to the bottom.

- Heat flows in water ( and gas) through convection.
