Does a litter of liquid equal a kilogram?

Question

if we put a bottle contains one litre of water on a balance does the balance reads one kgr

Answer 1

If you are specifically talking about water (as opposed to just any liquid), at 4 degrees C and 760 mm of mercury, and you're not also weighing the bottle, then the scale should read 1kg, yes.

But a liter is a unit of volume and a kilogram is a unit of mass, so you can't say the two are equal.

Answer 2

No, if you dont calibrate the balance using the weight of the bottle. Because the weight of the bottle will be taken into consideration by the balance

Yes, if it is calibrated using the bottle.

But then talking about the equivalence of 1 liter of water to 1 kg, it will be justified by the equation m = dv if and only if the density of the liquid is 1.00 g/ml that is for a pure water. Thus making mass = volume.

Answer 3

that depends of the temperature and pressure the water bottle is in. to find put the mass you have to use the equation m= d x V (mass=density x volume). What happens is that the density of water varies a little, almost nothing. At room temperature the density of water is about .998 g/cm3 (that´s cube centimeters).

So if we´re talkin about water in standard conditions (25C and 1Atm of pressure) 1 liter of water weighs .998 kilograms. Most people round the density up to 1 but if u want to be precise then use the actual density.

By the way the density of water is 1 at 4 degrees Celcius

Answer 4

The definition of a kilogram is the mass of pure water at sea level and at 4C that fills a cubic volume of 1000 cubic centimetres, or a litre. Conversly the definition of a litre is the volume of water masing 1 kilogram at 4C and at sea level.

So, yes, proveided the criteria as outlined above are met.

Answer 5

yes, only if you have tared the balance with the empty bottle and the temperature of water is 4 degree and atmospheric pressure is 1 atm.

Answer 6

Yes, if the bottle weight is tared out. 1 liter of water weighs 1 kg, unless it is very salty.

Answer 7

Pure Water, 1 litre. YES.
The water must be 4 deg.Celcius too.


Pure Water, 1 litre, one bottle. NOT 1kg.

Answer 8

to calculate that u have to know the density of the liquid
m=dv

where :
m= mass
d=density
v=volume

for water having a density of aproximately 1g/ml
m = 1g/ml*1000ml = 1000g= 1 kg

u can also look for the density of the water on net for the exact value it also depends on the temperature density decrase with the increasing temperature

Answer 9

It will read more because of the mass of the container.
If the contents are good, clean water, then the water itself will give a mass of 1kg.

Answer 10

Only at 4 deg celcius for pure water.
