Its density
You would weigh more in the air than in the water due to the buoyant force acting against your weight in the water. In water, your body experiences an upward force opposing gravity, causing you to feel lighter. This effect makes you weigh less in water compared to being in the air.
Objects under water seem to weigh less but they have the same mass as they would out of water.
you would weigh 200 lbs. in water as you would on land. Your body just moved the water out of the way, which explains displacement. Buoyancy is what makes you seem lighter though. Because you weigh more than the water that you displaced and because the the water that you moved has a weight too, your body would be forced up after moving the water out of the way. So it's not that you weigh less in the water if someone picks you up, they just have more help when lifting you.
You may weigh less after a shower because the water on your body adds weight, and some of it is lost as the water evaporates.
Yes, diesel fuel is heavier than water. Water has a density of 1 gram per cubic centimeter, while diesel fuel has a density of about 0.85-0.90 grams per cubic centimeter. This means that diesel fuel will sink in water.
because there's less water in it.
It makes something weigh more or weigh less. Also it makes something stay in the planet's atmosphere.
no
No. Oil is less dense than water, so 1 liter of oil will weigh less than 1 liter of water.
You may weigh less after a shower because the water on your body evaporates, removing some weight temporarily.
Gravitational Pull
Fish weigh less in water because of buoyancy, which is the upward force exerted by a fluid that counteracts the weight of the object immersed in it. The water exerts an upward force on the fish that partially cancels out the downward force of gravity, making the fish weigh less in water than in air.
