Main Question or Discussion Point
Why?
Always slipping through your fingers?Well, idk. You're able to easily move it around and stuff but when you try to pick it up it takes effort.
Would that make it heavy?Always slipping through your fingers?
no, it's not easy to move around. Its inertial mass and gravitational mass are the same.Well, idk. You're able to easily move it around and stuff but when you try to pick it up it takes effort.
Water moves around things because it is a fluid. (It is also a liquid)Would that make it heavy?
How HEAVY something may be is related directly to its mass.In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress.
Oh, ok. Well then can you explain that to me? Because a balloon full of air and a balloon full of water the same size basically look similar, but the one with water is much heavier. How is that so if they're taking up the same amount of space? Stupid question, I know.Water moves around things because it is a fluid. (It is also a liquid)
To quote wiki:

For a gas like helium in a balloon, there are FAR fewer atoms of helium that will fit in the balloon compared with water. This isn't because helium is "larger", it is because helium is a gas normally. The atoms are flying around very quickly and don't stick together at all like water does. Water molecules attract each other and are much heavier than helium atoms are, so they are much harder to turn into a gas. (Which is why water is a liquid all the way up to 100 Celsius while helium is a gas unless you cool it to around -270 Celsius)Oh, ok. Well then can you explain that to me? Because a balloon full of air and a balloon full of water the same size basically look similar, but the one with water is much heavier. How is that so?
My troll detector goes "ping". This is a question children in preoperational stage may ask - that means, up to 7 y.o.Because a balloon full of air and a balloon full of water the same size basically look similar, but the one with water is much heavier. How is that so if they're taking up the same amount of space?
I'm going to assume no troll, and say the answer is density. You can imagine the water balloon has got more stuff inside, even though it has same volume as the air balloon. The ratio of 'stuff' to volume is density. (Or, more technically than 'stuff', I should say mass). In an equation:Oh, ok. Well then can you explain that to me? Because a balloon full of air and a balloon full of water the same size basically look similar, but the one with water is much heavier. How is that so if they're taking up the same amount of space? Stupid question, I know.
