How Can I Prove That 1 Litre Of Water Is Not Equal To 1000g On A Scale

Why does a litre of water weigh 1kg but a litre of ice cream weigh only like 560 gms? Is it just because of empty space?

First of all, we need to know what goes into ICE CREAM. Ingredients such as milk, cream, and sugar. But there is another important ingredient that we cannot see - AIR. Air makes up anywhere from 30% to 50% of the total volume of ice cream.Ice cream is an emulsion — i.e., a combination of two liquids that don't normally mix together. Instead, one of the liquids is dispersed throughout the other. In ice cream, 'fat globules' (liquid particles of fat) — are spread throughout a mixture of water, sugar, and ice, along with air bubbles. The structure of ice cream is porous. A typical air pocket in ice cream will be about one-tenth of a millimeter across. The presence of air means that ice cream is also a foam - a substance formed by trapping pockets of gas in a liquid or solid.The amount of air added to ice cream is known as overrun. If the volume of ice cream is doubled by adding air, then the overrun is 100%, which is the maximum allowable amount of air that can be added to commercial ice cream. The less expensive brands usually contain more air than the premium brands. One side effect of adding a lot of air to ice cream is that it tends to melt more quickly than ice cream with less air.The amount of air also has a huge effect on the density of ice cream. As a rule of thumb, one litre of commercially made ice cream must weigh around 540g, making the minimum density 0.54 gram per milliliter. Better (more expensive) brands have higher densities—up to 0.90 grams per milliliter. We can compare cheaper and more expensive brands by holding a carton in each hand — we can notice a difference.Due to the high fat content of ice cream, however, and because fat is less dense than water, any ice cream will always be less dense than any aqueous solution.

Why is it that 1 litre of water weighs 1 kg while this doesn't apply for other liquids?

Only a few people have explained it correctly. It was DEFINED that way. Others tried to act superior by talking about Density, and giving equations relating Mass, Density and Volume. Sincerely, do you people think that the guy who posted the question does not know what density is? It is obvious he was alluding to how 1 L of water weighed exactly 1 Kg.1 L of water weighing 1 KG is kind of creepy coincidence.And he wanted that coincidence explained. Not given lectures on what density is!

Is 1 ml equal to 1 mg? If not, why?

Because it totally depends on density.Relation between mass, volume and density of liquid isVolume = Mass/Densityor Mass = Volume*DensityIn this case mass is changes with density though the volume is same. In other word same volume of different liquids will give you different mass. So 1 mL of different liquid will give different mg of mass. Even mass of 1 mL of same liquid will vary at different temperature. Only In case of pure water: At four degree celsius mass of 1L pure water is 1kg.so, 1L=1000mL=1kg=1000g=1000000mgFrom above equation you will get 1mg = 0.001mL or 1mL = 1000mg

Is one kg oil equal to one liter?

Litre is the unit of Volume.1 litre = 10 cm x 10 cm x 10 cm = 1000 cm^3 .1 litre of water = 1 kg weight.Density of oil is less than that of water that's why oil floats in the water.Density of oil is about 90% of water density. So the specific gravity of oil is almost 0.9Density of water = 1 kg / litreSo density of oil = 0.9 kg /litreIt means0.9 kg oil = 1 litre oil1 kg oil = (1/0.9) litre = 1.1 litre .

Does 1 litre of all liquids equate to a weight of 1 kilogram?

You asked: "Does 1 litre of all liquids equate to a weight of 1 kilogram?"There are already several (6 at the time) fairly good answers to your question here. Unfortunately most of them are fundamentally flawed, but that is not their fault. The problem is that they tried to answer your question exactly as you asked it. The question misleads most of the other answers, well intentioned as they are.You see, you asked a question about the relationship of 1 litre to 1 kilogram. Good question.  But you asked about "weight", and a kilogram is NOT a measure of WEIGHT, it is a measure of "mass".  Mass refers to how much of some substance of whatever substance you are considering.  In effect the number of atoms. A litre is a measure of space, which, if that space contains ordinary water (not so heavily blended with salts that it would be called "sea water") if that water is at a temperature of 4 degrees on the Celsius scale of temperature. Water expands, taking up more space as the molecule bump into each other due to their higher energy level (energy of the heat).  So a litre of water at 0 degrees Celsius is a little smaller than a liter of space, even though a litre of space is defined quite clearly as a kilogram of water, but ONLY if the water is at exactly 4 degrees Celsius.As already discussed a little bit above, temperature affects how dense a liquid will appear to be, and different liquids have different starting points of density because a different number of atoms would occupy the space defined as a litre. The substance Mercury, a slivery looking liquid, which actually LOOKS silvery because it is a liquid at room temperature, but it actually also metal like copper or tin or silver. At this high density the liquid metal would weight a great deal more than 1 kilogram if you had a whole liter of it.  A liter of Mercury would amount to 13.53 kilograms (not 1 kilogram like water).Of course if you get things very, very hot, for example steel, you can met it into a liquid too . A litre worth of molten, liquid steel would also have a mass a great deal more than a litre of water. Now because it needs to be 2,500 degrees Fahrenheit to melt, it would be less dense than cold steel.  Does that help you to understand the relationship between the volume measure of 1 liter, and the mass of 1 kilogram is 1 liter of water, but only if that is pure water and the water is at a temperature of 4 degrees Celsius.I do hope that helps.Sincerely,Stafford "Doc" Williamson

Chemistry help on heat and energy problems!!?

1)
m₀ = mass of the body = 93kg
C = specific heat capacity of water = 4.0 J/g.℃
ΔT = temperature change = 0.90℃

m₁ = mass of water evaporated
L = heat absorbed per gram = 2.44 kJ /g

Heat lost by the body
H = m₀C*ΔT
H = (93kg x 1000g/1kg) (4.0 J/g.℃) (0.90℃)
H = 334800 J
`````````````````
heat absorbed by the sweat
H = m₁L
H = m₁(2.44 kJ/g * 1000g /1kg)
H = 2440m₁ J

Heat lost by the body = heat absorbed by the sweat
334800 J = 2440m₁ J
m₁ = 137g
````````````````

2)
Heat absorbed by the water;
C = 4.18 J/g.℃

H = m₀C*ΔT
H = (1.08kg)(4.18 J/g.℃)(100℃ - 35.0℃)
H = (1080g)(4.18 J/g.℃)(100℃ - 35.0℃)
H = 293436 J
H = 293.436 kJ

Heat produced by natural gas
H = m₁L
H = m₁(49.3 kJ/g)

Heat produced by natural gas = Heat absorbed by the water
m₁(49.3 kJ/g) = 293.436 kJ
m₁ = (293.436 kJ) / (49.3 kJ/g)
m₁ = 5.95 g of natural gas

How many kilos of water in 50 Gallon ? What would be the weight of the water of?

The mass of water is 1000g per litter at +4ºC
Above and below the density decreases
1 gallon UK 4.54609 liters

Why is water hardness measured in terms of CACO3?

The hardness of water is expressed in terms of ppm because the molecular weight of calcium carbonate is 100gm/mol. It is easy to calculate. This is one of the main reason for expressing the hardness of water in ppm. Also calcium carbonate is insoluble in water therefore it is easy to calculate its amount in water.The hardness is not entirely due to calcium – magnesium is usually present to some extent and other multivalent cations. When the hardness is expressed as CaCO3, it is calculated as if the magnesium, etc. were there as calcium. It also includes the bicarbonate ions such as chloride, sulphate and nitrate.

How many newtons are equal to 1 kg?

It depends upon the planet you are in.Newton is the unit of Force.Force=mass*accelerationHere acceleration is g. So as g changes F changes keeping mass constant.Here on earth, g is approximately 9.8 m/s*s .Therefore F=(1*9.8) newtonThat is 1kg =9.8N.Hope that helps!
