If they both weigh a kilogram then they both weigh the same... a kilogram. It's like asking if a pound of feathers weighs more then a pound of rocks... they both weigh a pound.
13.7 times more. Because the atoms of mercury are heavier (more massive) than the molecules of water AND they're closer together.
Indeed it does, especially if it's over one kilogram
because neptune has more mass than mercury
Being on Mercury will change your weight because you would be pulled down with a smaller force. You would weigh on Mercury 0.38 time your weight on Earth.
they would weigh more. more gravity= more weightadd. With a smaller gravity, they would weigh LESS.
Both would weigh 1 Kilogram with a difference of volume.
You're comparing a mass to a volume. A gallon of water can can weigh a certain amount, but a gallon of a more dense fluid can weigh more.
13.7 times more. Because the atoms of mercury are heavier (more massive) than the molecules of water AND they're closer together.
They both weigh 1 kilogram.
1 cubic decimeter of pure water is 1 liter and weigh 1 kilogram. A mass of one kilogram is a weight of one kilogram at sea level. If you move your subject into space, it will weigh less. If you take it to Jupiter, it will weight more, but its mass will remain one kilogram.
Yes
No!
It does not.It does not.It does not.It does not.
yes, 1200 grams weighs 2oo grams more than a kilogram. a kilogram is 1000 grams.
Please note that a kilogram is a unit of mass - NOT a unit of weight. And yes, a pencil has a mass that is considerably less than a kilogram. For comparison, a kilogram is the mass of a liter of water.
Neither. They both weigh the same.
Indeed it does, especially if it's over one kilogram
