You would cool a bucket by putting ice into the water.
since you're probably talking about the volume of water in the bucket, you could use either ml or liters (1 liter is 1000 ml), grams are a measure of weight and meters measure length.
The weight per US gallon of water at 25 C is 8.33 pounds [per gallon. 2 gallons of water would weigh 16.66 pounds plus the weight of the bucket itself.
A standard household bucket is measured in litres.
Weight(mass) is measured in kilograms.
Gallons
The SI (Systeme Internationale or 'Metric') unit of Mass is the Kilogram A standard bucket (c. 5 gallons) of water would have a mass of approximately 25Kg, so the Kilogram would be scientifically correct, as well as scale-appropriate. Note that the Kilogram is not a unit of Weight - the Metric unit of weight is the Newton, N and represents the force exerted by the mass due to the force of gravity. That is, even on the moon, the bucket would still have a Mass of 25Kg (No, really!), but its Weight would be drastically reduced due to the greatly reduced gravity.
The change in water would depend on how heavy the body is. If the body is 60 mg. In wieght the water would go up 60 ml.
it would not.
you cannot measure it all because that would be impossible but you could get a bucket and when it rains afterwards you may see how much the water has increased to and measure it

How large is the bucket? I would suggest pouring water in to find out.
