Is a single property such as density sufficient to always correctly identify substance?
can density always correctly identify a substance
What are two ways to compare the density of a unknown substance?
One way is using the formula D=m/v. Or you could get some water and put the substance inside the water and see if the density is lower or higher.
Is density an example of a chemical change?
No, density is simply a property of a substance. It's how "heavy" something is. Water, for example, has a density of 1 gram per milliliter. Meaning every milliliter weighs one gram. Some are much more (Mercury), some are much less (Air).
What is a unit used to measure the amount of chemical substance?
The answer is Density. It is a Characteristic property and measured by grams per cubic centimeter.
Is it true that if you divide the mass of a substance by its volume you can find its density?
Yes. if you have a mass of 4 ml of water, and it weighs 4 grams, the density of water is 1 gram per millileter. The common unit for density is g/ml or g/cm^3. But when weighing a liquid, remember to tare the glassware you are holding the liquid in while weighing it, or your density will be incorrect due to a false mass measurement. But given a mass and a volume of a substance, the density is just mass over volume.
What are some economic transformations from 1960-1979?
they increased and decreased according to the unstability of the economy
What the formula for relative density?
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.
What the effect of shabu?
Some of the effects of shabu includes increased talkativeness, increased wakefulness and activity, and increased attention. Decreased fatigue is also one of the effects of shabu.
What were some results of Britain's Agricultural Revolution?
The overall population increased and food costs decreased.
How will the density change if the temperature increased to 125?
The density of most substances will change if temperature is increased. The amount of change depends on the difference between the two temperatures.
What does specific gravity measure?
It's basically equivalent to density. More precisely, it's the ratio of the density of a substance, to the ratio of water (or some other reference substance).
What is the relashonship between scpecific gravity and density?
The specific gravity of a substance (as an example, I'll take iron) is the density of iron divided by the density of water. Or some other reference substance - but usually the comparison is with water.
How do you use mass density in a sentence?
'The term relative density or specific gravity denotes the ratio of the mass of a certain volume of a substance to the mass of the same volume of some standard substance.' Or, 'The density in this town keeps rising because of our population.'
Why do some very lucky people have the inability to gain weight?
Some people have thyroid problems which causes their metabolisms to be dramatically increased/decreased. xxxRucaxxx
Is a single property such as density sufficient to always correctly identify substance?
can density always correctly identify a substance
Volume and pressure are held constant why does the hot air balloon rise and fall?
Although volume and pressure are held constant, some of the gas escapes from the bottom of the balloon, thus decreasing the mass of the gas in the balloon. If mass is decreased, then density is also decreased because density=mass/volume. Such a decrease in density of the balloon causes it rise.
What are two ways to compare the density of a unknown substance?
One way is using the formula D=m/v. Or you could get some water and put the substance inside the water and see if the density is lower or higher.
