I haven't tried it, but theoretically it's not true.
Ice is a crystalised, low temperature water. So the more temperature you give it, the faster it's mollecules gain enough kinetic energy to break it's bonds and liquify.
Ofcourse, giving too much temperature (like dropping it into few hundred degrees) would cause it to turn directly into gas, therefore forming a thin layer of gas that prevents direct contact between ice and hot water
Ice cubes don't faster in cold water because the temparature of cold water is low, ice cubes melt faster in high temparature.
if it is hot water it tends to melt faster but if it is cold water it wont melt quickly
It melts faster in cold
yes.
Yes.
Most probably , it would be fresh water. This is because since there is no salt which would keep the cold , the fresh water would melt faster.
No heat so it cant melt like the warm water. they are the same temp/.
Yes, water will melt faster on a very cold soft drink can. This is due to evaporation, which tends to become expedited during cold and frigid temperatures.
It depends if its hot water but it will still melt faster in cold water tha the air.
sunlight will
It depends on how hot/cold your water is, and how hot/cold room temperature is.
