ANSWER: yes
Goldfish breathe slower in cold water because there is more oxygen in cold water. Therefore they don't have to breathe as much to get the amount of oxygen they need
cold water faster

No, hot water heats up faster than cold water.
You can breathe in either. Given a normal environment both hot and cold water will evaporate and become water vapour (change from a liquid to a gas). All else being equal the hot water will evaporate faster, but the cold water will still evaporate. For example, when you sweat, your sweat is not particularly hot, but it is the evaporation of the sweat that cools you down. You can therefore breathe in the water vapour from either hot or cold water. Just for absolute clarification - the above assumes the questioner is not asking if you can breathe under water; which clearly you can't unless there is something a little fishy about your character! :-)
No, hot water heats up faster than cold water.
hot water has faster moving particales than cold water
Ice cubes don't faster in cold water because the temparature of cold water is low, ice cubes melt faster in high temparature.
Cold water
It sinks faster in hot water than warm or cold
Sugar sinks at the same rate in warm or cold water. Sugar dissolves faster in warm water.
