AIM - OBSERVE CONVECTION IN A LIQUID

METHOD - 1. SET UP A BUNSEN BURNER ON A HEATPROOF MAT. PUT THE GAUZE                                 MAT ON A TRIPOD BUT LEAVE IT JUST TO ONE SIDE OF THE BUNSEN                               BURNER
                     2. FILL A 200 mL BEAKER WITH 150 mL COLD WATER
                     3. PLACE THE BEAKER ON TOP OF THE TRIPOD AND GAUZE AND ALLOW                           IT TO SETTLE FOR A FEW MINUTES
                     4. CAREFULLY INSERT A DRINKING STRAW DOWN ONE SIDE OF THE                                   BEAKER, BUT BE CAREFUL AS YOU DONT WANT TO DISTURB THE                                   WATER TOO MUCH
                     5. USING TWEEZERS , DROP A CRYSTAL OF POTASSIUM PERMANGANATE                           DOWN THE INSIDE OF THE STRAW. WAIT FOR THE CRYSTAL TO                                         SETTLE ON THE  BOTTOM OF THE BEAKER
                     6. VERY GENTLY, SO TO NOT DISTURB THE WATER,REMOVE THE STRAW
                     7. LIGHT THE BUNSEN BURNER AND SLIDE IT UNDER THE TRIPOD SO                                 THAT YOU ARE ONLY HATING THE OUTSIDE OF THE BEAKER WHERE                             THE CRYSTAL IS. OBSERVE
