submerge the bottle in cold water.
i would think salty water would melt it fasterbutterfly10
dark color melt it faster
Ice cube requires heat to melt.Water conducts heat well. Therefore the temperature of the environment is absorbed by the water and the some of the distributed heat is taken by the cube and it melts.Air is an insulator. The only way heat from surroundings can go to the ice cube INSIDE the water bottle is by convection of air currents. But the convection is restricted to some extent by the almost closed water bottle, which has high(compared to cube size) plastic walls (plastic: heat insulator) on all sides and a narrow mouth. Therefore the convection and thus passing of heat to cube from surroundings is slow and this makes the ice melt slower in the empty water bottle.
water
it really all depends on the temperature if the water is warmer than the ice it would melt in atleast 1 min if the water is freezing cold and colder than the ice then the ice will melt in an hour b/c the water will warm up to room temperature if it5 was boiling water it would obviosly melt in a few seconds or 2

i THINK water
Dissolves water
put it in a microwave oven
it will depend on which of these waters is hotter. the hotter the water the faster the ice will melt. doesn't matter if the water is fresh or salty. its the temperature of the water that will determine how fast the ice melts.
Does ice melt faster in sun or shade
dark color melt it faster
a ice cube in alcohol would melt fastest because of the heating molecules contracting with the ice cube molecules
under a light
Cold water will not melt the ice cube in record time, but hot water will, but salt water will also melt it fast, but if you add both together the ice cube will melt alot fast. Deceasing time alot.
Warm air and warm water. Cold air and cold water keep ice cooler longer.
