What ball will drop first in hot water or cold water?
a steel ball bearing will drop faster in warm water then cold water, a beach ball will float better in cold water because cold water is more dense.
Why does a beach ball float on the surface of the swimming pool?
A beach ball full of air can be compared to aballoon full of helium. The overall weight of the beach ball with the air in it is less then that of the water. Water is able to move to one side so if you submerge the beach ball and let go of it the the water will move aside and under it because it is heavier. A balloon full of helium will do the same in air until it is lighter then the air underneath, but heavier then that above it.
Does crushed paper ball float or sink in water?
float
Why does a grape float in salt water?
it floats because salt has chemicals so it can float like in the beach it's salt water right,so that's how you could float in the beach.
How do you know a substance will float?
If a certain volume of something (like a beach ball) was the same as a certain amount of water(water the size of the beach ball), but it weighs less, than it will float. An ordinary marble weighs a lot for it's tiny size, and in that case it will CERTAINLY sink in water. Everything that I said about an amount of something weighing a certain amount of g/kgs/tonnes, is called 'Density', like planet Saturn. This planet is the densiest and CAN float on water if it could...
Whould an aluminum ball sink or float?
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
Can plastic ball float on water?
Yes.
Does a ball float in water higher than in oil?
No, a ball will float higher in oil than in water because the density of oil is lower than that of water. The buoyant force experienced by the ball in oil is greater, causing it to float higher.
How does density relate to a object sinking or floating?
Answer: It doesn't matter about the size, it matters about the weight. If an beach ball weigh .2280 grams, and a golf ball weighs 1.258 lbs., the golf ball will sink but the beach ball will float. Even though the beach is bigger than the golf ball.
How do you measure density of bowling ball?
Float the ball in water and calculate the displacement.
Does a plasticine ball float on water?
no
Why can't a balloon rise and leaves earth's atmosphere?
For the same reason that a beach ball can rise high in the water but can't leave the water. A balloon is floating in air. If there is no air around it, then it has nothing to float in.
